SUMMARY PROSPECTUS

Royce Micro-Cap Fund

MAY 1, 2013 Investment Class Symbol: RYOTX \| Service Class Symbol: RMCFX




Investment Goal Royce Micro-Cap Fund’s investment goal is long-term growth of capital. Fees and Expenses of the Fund The following table presents the fees and expenses that you may pay if you buy and hold shares of the Fund.
SHAREHOLDER FEES (fees paid directly from your investment)

	Investment Class		Service Class

Maximum sales charge (load) imposed on purchases		0.00%		0.00%

Maximum deferred sales charge		0.00%		0.00%

Maximum sales charge (load) imposed on reinvested dividends		0.00%		0.00%

Redemption fee (as a percentage of amount redeemed on shares held for less than 180 days)		1.00%		1.00%


ANNUAL FUND OPERATING EXPENSES (expenses that you pay each year as a percentage of the value of your investment)

Management fees		1.30%		1.30%
Distribution (12b-1) fees		0.00%		0.25%
Other expenses		0.17%		0.19%
Acquired fund fees and expenses		0.02%		0.02%

Total annual Fund operating expenses		1.49%		1.76%

Fee waivers and/or expense reimbursements		0.00%		(0.08)%

Total annual Fund operating expenses after fee waivers and/or expense reimbursements		1.49%		1.68%

Royce has contractually agreed, without right of termination, to waive fees and/or reimburse expenses to the extent necessary to maintain the Service Class’s net annual operating expenses, other than acquired fund fees and expenses, at or below 1.66% through April 30, 2014. Total annual Fund operating expenses may differ from the expense ratio in the Fund’s Financial Highlights because the highlights include only the Fund’s direct operating expenses and do not include acquired fund fees and expenses, which reflect the estimated amount of the fees and expenses incurred indirectly by the Fund through its investments in mutual funds, hedge funds, private equity funds, and other investment companies.
EXAMPLE

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s total operating expenses (net of fee waivers and/or expense reimbursements for the Service Class in year one) remain the same. Although your actual costs may be higher or lower, based on the assumptions your costs would be:

	Investment Class		Service Class

1 Year		$152		$171

3 Years		$471		$546

5 Years		$813		$947

10 Years		$1,779		$2,067

Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 15% of the average value of its portfolio.

Royce Micro-Cap Fund

Principal Investment Strategy
Royce & Associates, LLC (“Royce”), the Fund’s investment adviser, invests the Fund’s assets primarily in the equity securities of micro-cap companies, a universe of more than 3,000 companies with stock market capitalizations up to $750 million. Using its value approach, Royce generally focuses on micro-cap companies that it believes are trading significantly below its estimate of their current worth. This assessment is based chiefly on balance sheet quality and cash flow levels.
Normally, the Fund invests at least 80% of its net assets in the equity securities of micro-cap companies. Although the Fund normally focuses on the securities of U.S. companies, it may invest up to 35% of its net assets in foreign securities. While the Fund anticipates that its investment in foreign securities will generally be in securities of companies that are headquartered in “developed countries,” the Fund may also invest up to 10% of its net assets in the securities of companies that are headquartered in “developing countries.” Developing countries, sometimes also referred to as emerging markets countries, include every country in the world other than the United States, Canada, Japan, Australia, New Zealand, Hong Kong, Singapore, South Korea, Taiwan, Bermuda, and Western European countries (as defined in the Fund’s Statement of Additional Information).
In selecting securities for the Fund, Royce uses a bottom-up, value approach. Royce primarily focuses on company-specific criteria rather than on political, economic, or other country-specific factors. The Fund may sell securities to, among other things, secure gains, limit losses, redeploy assets into what Royce deems to be more promising opportunities and/or manage cash levels in the Fund’s portfolio.

Primary Risks for Fund Investors
As with any mutual fund that invests in common stocks, Royce Micro-Cap Fund is subject to market risk—the possibility that common stock prices will decline over short or extended periods of time. As a result, the value of your investment in the Fund will fluctuate, sometimes sharply and unpredictably, and you could lose money over short or long periods of time.
     The prices of micro-cap securities are generally more volatile and their markets are less liquid relative to larger-cap securities. Therefore, the Fund may involve considerably more risk of loss and its returns may differ significantly from funds investing in larger-cap companies or other asset classes.
     Investment in foreign securities involves risks that may not be encountered in U.S. investments, including adverse political, social, economic, or other developments that are unique to a particular region or country. These risks may be heightened for developing markets securities. Prices of foreign securities in particular countries or regions may, at times, move in a different direction and/or be more volatile than those of U.S. securities. Because the Fund does not intend to hedge its foreign currency exposure, the U.S. dollar value of the Fund’s investments may be harmed by declines in the value of foreign currencies in relation to the U.S. dollar.
     Royce’s estimate of a company’s current worth may prove to be inaccurate, or this estimate may not be recognized by other investors, which could lead to portfolio losses. To the extent the Fund overweights a single market sector or industry relative to its benchmark index, its performance may be tied more directly to the success or failure of a relatively smaller or less well-diversified group of portfolio holdings.
     Investments in the Fund are not bank deposits and are not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance
The following performance information provides an indication of the risks of investing in the Fund. Past performance does not indicate how the Fund will perform in the future. The Calendar Year Total Returns chart shows performance year by year over the last ten years (Investment Class used for illustrative purposes—returns differ by Class). The Annualized Total Returns table shows how the Fund’s average annual total returns for various periods compare with those of the Russell Microcap Index, the Fund’s benchmark, and the Russell 2000 Index. Each Class has substantially similar returns because all invest in the same portfolio of securities, differing only to the extent that the Service Class has higher expenses than the Investment Class.
The table also presents the impact of taxes on the Fund’s returns (Investment Class again used for illustrative purposes; after-tax returns would have been lower for the Service Class). In calculating these figures, we assumed that the shareholder was in the highest federal income tax bracket in effect at the time of each distribution of income or capital gains. We did not consider the impact of state or local income taxes. Your after-tax returns depend on your tax situation, so they may differ from the returns shown. This information does not apply if your investment is in an individual retirement account (IRA), a 401(k) plan, or is otherwise tax deferred, because such accounts are subject to income taxes only upon distribution. Current month-end performance information may be obtained at www.roycefunds.com or by calling Investor Services at (800) 221-4268.
