FEES AND EXPENSES OF THE FUND

The tables below describe the fees and expenses that you may pay if you buy, sell or hold Investor Class shares of the Fund.

SHAREHOLDER FEES (fees paid directly from your investment)	Investor Class Shares

Other Expenses	0.53%
Total Annual Fund Operating Expenses1	2.48%

¹  The Advisor has contractually agreed to reimburse the Investor Class shares of the Fund for Total Annual Fund Operating Expenses in excess of 2.25% until at least January 31, 2014 (excluding interest, dividend expense on short sales/interest expense, taxes, brokerage commissions, other investment related costs and extraordinary expenses).

EXAMPLE

This example is intended to help you compare the cost of investing in the Investor Class of the Fund with the cost of investing in other mutual funds. The example assumes that you invested $10,000 in the Investor Class of the Fund for the time periods indicated and then redeemed all of your shares at the end of those periods. The example also assumes that your investment had a 5% return each year and that the operating expenses (as a percentage of net assets) of the Fund’s Investor Class remained the same. The example reflects contractual fee waivers and reimbursements through January 31, 2014. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

	1 Year		3 Years		5 Years		10 Years
International Opportunities Fund — Investor Class	$	228	$	751	$	1,300	$	2,799

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). Higher portfolio turnover 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 41% of the average value of its portfolio.

PRINCIPAL STRATEGIES

The Fund invests primarily in foreign micro cap companies.

Under normal market conditions, we will invest the Fund’s assets in equity securities of foreign companies with market capitalizations of less than US$1 billion at the time of purchase. Under normal market conditions, the Fund will invest in at least five of the countries included in the Morgan Stanley Capital International (MSCI) All Country (AC) World Ex-U.S.A. Small Cap Index.

The Fund may invest a significant amount of its total assets (20% to 70% under normal market conditions) at the time of purchase in securities issued by companies domiciled in emerging markets. Emerging market countries are those currently included in the MSCI EFM (Emerging + Frontier Markets) Index. These companies typically are located in the Asia-Pacific region, Eastern Europe, the Middle East, Central and South America, and Africa.

We travel extensively outside of the U.S. to visit companies and expect to meet with senior management. We use a process of quantitative screening followed by “bottom up” fundamental analysis to identify individual companies that we believe have above average revenue and earnings growth potential. We may invest in early stage companies if we believe they have outstanding long-term growth potential.

We do not use allocation models to restrict the Fund’s investments to certain regions, countries or industries.

The Fund may invest a large percentage of its assets in a few sectors, including industrials, consumer discretionary, information technology, materials, consumer staples, energy, financials and health care.

The Fund may also invest in initial public offerings (IPOs).

PRINCIPAL RISKS

All investments carry some degree of risk that will affect the value of the Fund, its investment performance and the price of its shares. As a result, you may lose money if you invest in the Fund.

The Fund is subject to the following principal investment risks:

Stock Market Risk. The Fund’s investments may decline in value due to movements in the overall stock market.

Stock Selection Risk. The Fund invests primarily in equity securities (including common stock, preferred stock and securities convertible into common stock, warrants and rights, and other securities with equity characteristics). The Fund’s investments may decline in value even when the overall stock market is not in a general decline.

Foreign Securities Risk. Foreign securities are generally more volatile and less liquid than U.S. securities. Further, foreign securities may be subject to additional risks not associated with investment in U.S. securities due to differences in the economic and political environment, the amount of available public information, the degree of market regulation, and financial reporting, accounting and auditing standards, and, in the case of foreign currency-denominated securities, fluctuations in currency exchange rates.

Emerging and Frontier Markets Risk. In addition to the risks of investing in foreign securities in general, the risks of investing in the securities of companies domiciled in emerging and frontier market countries include increased political or social instability, economies based on only a few industries, unstable currencies, runaway inflation, highly volatile securities markets, unpredictable shifts in policies relating to foreign investments, lack of protection for investors against parties that fail to complete transactions, and the potential for government seizure of assets or nationalization of companies.

Micro Cap Company Stock Risk. Micro cap stocks may be very sensitive to changing economic conditions and market downturns because the issuers often have narrow markets, fewer product lines, and limited managerial and financial resources, resulting in volatile stock prices and a limited ability to sell them at a desirable time or price.

Early Stage Companies Risk. Early stage companies may never obtain necessary financing, may rely on untested business plans, may not be successful in developing markets for their products or services, and may remain an insignificant part of their industry, and as such may never be profitable. Stocks of early stage companies may be illiquid, privately traded, and more volatile and speculative than the securities of larger companies.

Growth Stock Risk. Growth stock prices may be more sensitive to changes in current or expected earnings than the prices of other stocks, and they may fall or not appreciate in step with the broader securities markets.

Sector Weightings Risk. Market conditions, interest rates, and economic, regulatory, or financial developments could significantly affect all the securities in a single sector. If the Fund invests in a few sectors, it may have increased exposure to the price movements of those sectors.

Initial Public Offerings (IPOs) Risk. IPOs involve a higher degree of risk because companies involved in IPOs generally have limited operating histories and their prospects for future profitability are uncertain. Prices of IPOs may also be unstable due to the absence of a prior public market, the small number of shares available for trading and limited investor information.

The table below is designed to help you evaluate your risk tolerance by showing the best and worst quarterly performance of the Fund’s Investor Class for the years shown in the bar chart.

After tax-returns are calculated using the historical highest individual federal marginal income tax rates, and do not reflect the impact of state and local taxes. Actual after-tax returns depend on the investor’s tax situation and may differ from those shown. The after-tax returns are not relevant to investors who hold Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

The Fund’s returns after taxes on distributions and sale of Fund shares may be higher than returns before taxes and after taxes on distributions because they include the effect of a tax benefit an investor may receive from the capital losses that would have been incurred.

TAX INFORMATION

The Fund intends to make distributions.

PAYMENTS TO BROKER-DEALERS AND OTHER FINANCIAL INTERMEDIARIES

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), the Advisor or its affiliates may pay the intermediary for the sale of shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your individual financial advisor to recommend the Fund over another investment. Ask your individual financial advisor or visit your financial intermediary’s website for more information.
