the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in stocks 
that are held in its benchmark index. The fund uses a full replication strategy, which involves investing 
substantially all of its assets in all of the stocks in the benchmark index, the MSCI EAFE Index Net 
(Index), in proportion to each stock&#x2019;s weight in the Index. T.&#160;Rowe Price compares the composition 
of the fund to that of the Index. If a material misweighting develops, the portfolio manager seeks to 
rebalance the portfolio in an effort to realign it with the Index. Any derivatives that provide exposure 
to the investment focus suggested by the fund&#x2019;s name, or to one or more market risk factors associated 
with the investment focus suggested by the fund&#x2019;s name, are counted (as applicable) toward compliance 
with the fund&#x2019;s 80% investment policy.&lt;/p&gt;&lt;p style="-sec-ix-redline:true;font-size:8.0pt; font-family:Arial; text-align:left; font-weight:normal; text-decoration:none;"&gt;The fund attempts to track the performance of stocks in developed 
non-U.S. markets by seeking to match the performance of the Index. The Index is a broadly diversified 
stock index designed to represent the performance of large- and mid-cap securities across developed markets, 
including countries in Europe, Australasia and the Far East, and excluding the U.S. and Canada. The Index 
assumes the reinvestment of dividends after the deduction of withholding taxes applicable to the country 
where the dividend is paid. The Index is weighted by market capitalization and the composition of the 
Index is rebalanced semi-annually. As of October&#160;31, 2024, the Index consisted of 731 securities.&lt;/p&gt;&lt;p style="font-size:8.0pt; font-family:Arial; text-align:left; font-weight:normal; text-decoration:none;"&gt;Because 
the fund typically holds securities in proportion to their weight in the Index, the fund may become nondiversified, 
as defined under the Investment Company Act of 1940, solely as a result of changes in the composition 
of the Index.&lt;/p&gt;&lt;p style="-sec-ix-redline:true;font-size:8.0pt; font-family:Arial; text-align:left; font-weight:normal; text-decoration:none;"&gt;While most assets are invested in common stocks, the fund may also purchase exchange-traded 
funds in an effort to minimize any deviations in performance from the Index. Exchange-traded funds would 
typically be used to help realign the fund&#x2019;s portfolio with the Index, gain broad market or sector 
exposure, or to reduce cash balances in the fund and increase the level of fund assets exposed to common 
stocks. &lt;/p&gt;

the returns of its benchmark index (referred to as &#x201c;tracking error&#x201d;) because the fund incurs fees

to the extent the fund is unable to fully replicate its benchmark index, which could result from changes 
in the composition of the index or the timing of purchases and redemptions of fund shares. Tracking error 
may increase if the fund needs to fair value any of its portfolio holdings since the index does not need 
to apply fair valuation to its underlying securities.&lt;/span&gt;&lt;/p&gt;</rr:RiskTextBlock>

adverse political developments, increases in government debt, and changes in fiscal, monetary, or trade
