a	Non-income producing.
b	All or a portion of these securities were on loan at September 30, 2010. Total market value of loaned securities at September 30, 2010 was $8,237,097.
c	A security for which market quotations are not readily available represents 0.0% of net assets. This security has been valued at its fair value under procedures established by the Fund’s Board of Directors.
d	Includes securities first acquired in 2010 and less than 1% of net assets applicable to Common Stockholders.
	TAX INFORMATION: The cost of total investments for Federal income tax purposes was $260,673,173. At September 30, 2010, net unrealized appreciation for all securities was $65,560,066, consisting of aggregate gross unrealized appreciation of $96,896,726 and aggregate gross unrealized depreciation of $31,336,660. The primary difference between book and tax basis cost is the timing of the recognition of losses on securities sold.
	Valuation of Investments:
	Investment transactions are accounted for on the trade date. Securities are valued as of the close of trading on the New York Stock Exchange (NYSE) (generally 4:00 p.m. Eastern time) on the valuation date. Securities that trade on an exchange, and securities traded on Nasdaq’s Electronic Bulletin Board, are valued at their last reported sales price or Nasdaq official closing price taken from the primary market in which each security trades or, if no sale is reported for such day, at their bid price. Other over-the-counter securities for which market quotations are readily available are valued at their highest bid price, except in the case of some bonds and other fixed income securities which may be valued by reference to other securities with comparable ratings, interest rates and maturities, using established independent pricing services. The Fund values its non-U.S. dollar denominated securities in U.S. dollars daily at the prevailing foreign currency exchange rates as quoted by a major bank. Securities for which market quotations are not readily available are valued at their fair value under procedures established by the Fund’s Board of Directors. In addition, if, between the time trading ends on a particular security and the close of the customary trading session on the NYSE, events occur that are significant and may make the closing price unreliable, the Fund may fair value the security. The Fund uses an independent pricing service to provide fair value estimates for relevant non-U.S. equity securities on days when the U.S. market volatility exceeds a certain threshold. This pricing service uses proprietary correlations it has developed between the movement of prices of non-U.S. equity securities and indices of U.S.-traded securities, futures contracts and other indications to estimate the fair value of relevant non-U.S. securities. When fair value pricing is employed, the prices of securities used by the Fund may differ from quoted or published prices for the same security. Investments in money market funds are valued at net asset value per share.
	Various inputs are used in determining the value of the Fund’s investments, as noted above. These inputs are summarized in the three broad levels below:
	Level 1 – quoted prices in active markets for identical securities
	Level 2 – other significant observable inputs (including quoted prices for similar securities, foreign securities that may be fair valued and repurchase agreements)
	Level 3 – significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments)
	The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. The following is a summary of the inputs used to value the Fund’s investments as of September 30, 2010:

	Level 1		Level 2		Level 3		Total
Common stocks		$260,500,301		$35,622,900		$36,294		$296,159,495

Repurchase Agreements:
The Fund may enter into repurchase agreements with institutions that the Fund’s investment adviser has determined are creditworthy. The Fund restricts repurchase agreements to maturities of no more than seven days. Securities pledged as collateral for repurchase agreements, which are held until maturity of the repurchase agreements, are marked-to-market daily and maintained at a value at least equal to the principal amount of the repurchase agreement (including accrued interest). Repurchase agreements could involve certain risks in the event of default or insolvency of the counter-party, including possible delays or restrictions upon the ability of the Fund to dispose of its underlying securities.

Securities Lending:
The Fund loans securities to qualified institutional investors for the purpose of realizing additional income. Collateral for the Fund on all securities loaned is accepted in cash and cash equivalents and invested temporarily by the custodian. The collateral maintained is at least 100% of the current market value of the loaned securities. The market value of the loaned securities is determined at the close of business of the Fund and any additional required collateral is delivered to the Fund on the next business day. The Fund retains the risk of any loss on the securities on loan as well as incurring the potential loss on investments purchased with cash collateral received for securities lending.

Other information regarding the Fund is available in the Fund’s most recent Report to Stockholders. This information is available through The Royce Funds (www.roycefunds.com) and on the Securities and Exchange Commission’s website (www.sec.gov).
