Example

This example is intended to help you compare the cost of investing in International Opportunities Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in International Opportunities Fund for the time periods indicated and then redeem all of your shares at the end of those periods, that your investment has a 5 percent return each year and that International Opportunities Fund's operating expenses remain the same as set forth in the table above. The example also assumes that the fee waiver agreement currently in effect expires September 30, 2025; therefore, amounts for 3-, 5- and 10-year periods do not include any adjustment to reflect any fee waivers or expense reimbursements. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio Turnover

International Opportunities 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 International Opportunities Fund's performance. During the most recent fiscal year, International Opportunities Fund's portfolio turnover rate was 38 percent of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, International Opportunities Fund invests at least 80 percent of its net assets (plus borrowings for investment purposes) in equity securities issued by foreign markets issuers. A foreign markets issuer is an issuer operating in any industry sector that derives at least 50 percent of its gross revenues or profits from goods or services produced in non-U.S. markets or from sales made in non-U.S. markets. Issuers in which International Opportunities Fund invests may have any market capitalization. Equity securities include common and preferred shares, warrants and other rights derivative of or convertible into common stocks, American Depositary Receipts (ADRs), and Indian participatory notes (generally an interest in a pool of Indian-listed securities that is traded exclusively outside India by non-Indian registered investors), as well as shares of mutual funds and exchange-traded funds (ETFs), each of which invests at least 80 percent of its net assets in similar securities issued by foreign markets issuers.

To manage International Opportunities Fund's portfolio, its sub-adviser generally seeks to identify more than 30 foreign markets securities that the sub-adviser considers as having the best opportunity for total return. To select specific investments, the sub-adviser is opportunistic, that is, looking for market inefficiencies using a proprietary quantitative investment process focused on bottom-up fundamental research. International Opportunities Fund is "non-diversified," which means that it may invest a higher percentage of its assets in a smaller number of issuers.

International Opportunities Fund also may utilize options in an attempt to improve the risk/return profile of International Opportunities Fund's returns. International Opportunities Fund also may for hedging purposes buy and sell forward foreign currency exchange contracts in connection with its investments.

Generally, International Opportunities Fund invests in foreign markets issuers in the countries represented by the MSCI ACWI ex USA Index. As of June 30, 2024, the MSCI ACWI ex USA Index comprised issuers from countries representing 22 developed markets and 24 emerging markets. International Opportunities Fund generally will be invested in issuers in fifteen or more foreign countries and fifteen or more industry sectors. However, International Opportunities Fund may be invested in securities from any country, any industry sector, or of any market capitalization amount.

Principal Investment Risks

It is possible to lose money by investing in International Opportunities Fund. An investment in International Opportunities Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Market, Industry and Specific Holdings. The share price of International Opportunities Fund may fall because of weakness in and external shocks to the stock markets, generally, weakness with respect to a particular industry in which International Opportunities Fund has significant holdings, or weaknesses associated with one or more specific companies in which International Opportunities Fund may have substantial investments.

Foreign Securities, including Emerging Markets Securities. International Opportunities Fund's investments in or exposure to foreign securities (including ADRs) may be adversely affected by political and economic conditions overseas, reduced liquidity, or decreases in foreign currency values relative to the U.S. dollar. The risks of foreign investing are heightened for securities of issuers in emerging market countries. Emerging market countries tend to have economic structures that are less diverse and mature and political systems that are less stable. They also are more susceptible to governmental interference, do not require issuers to publish quality current financial information, and tend to have less liquid and efficient trading markets than those of developed countries. The value of a foreign security may change materially at times when U.S. markets are not open for trading.

Opportunistic Stock Investing. Different investment styles periodically come into and fall out of favor with investors, depending on market conditions and investor sentiment. Strategies favoring growth stocks generally are more volatile than the overall stock market; strategies favoring value stocks typically carry the risk that market prices may never recognize their intrinsic values. As International

5

Opportunities Fund holds stocks focused on growing cash-flow characteristics, from time to time it could underperform other mutual funds that use alternative metrics in their valuation criteria.

Large- and Mid-Capitalization Securities. Securities issued by large- and mid-cap companies tend to be less volatile than securities issued by smaller companies. Larger companies, however, may not be able to attain the high growth rates of successful smaller companies, especially during strong economic periods, and may be unable to respond as quickly to competitive challenges.

Small- and Micro-Capitalization Securities. Investments in small- and micro-capitalization companies typically present greater risks than investments in larger companies and, as a result, the performance of International Opportunities Fund may be more volatile than a fund that invests only in large- and mid-cap stocks.

Liquidity Risk. To meet shareholder redemption requests and other cash requirements, International Opportunities Fund may have to sell certain portfolio securities at times when there may be few, if any, buyers, causing International Opportunities Fund to accept sale prices below the amounts that had been used by the fund to determine its net asset value.

Investment Strategies, Generally, and Quantitative Investment Risk. International Opportunities Fund's investment strategy is based on assumptions of market and investor behavior. There are risks that those assumptions are incorrect, become outdated, or do not apply to specific market and political events. In those cases, the investment strategy is likely not to operate as anticipated, causing a loss in the value of International Opportunities Fund's portfolio. International Opportunities Fund's quantitative investment model is more complex than a typical non-quantitative strategy, and thus, may be less predictable in how it may react to specific market or political events.

Risks of Investing in ADRs. The risks of investing in ADRs include the risks of investing in individual U.S. equities, but they also include risks associated with investing in foreign equities. In addition, an ADR may not track the price of its associated underlying foreign security.

Currency and Option Contracts and Other Derivatives. International Opportunities Fund's investments in currency futures, forwards, options and other derivative instruments are subject to a number of risks, such as counterparty risk, the risk of mispricing or improper valuation, and the risk that the value of the instrument may not increase or decrease as expected. Options contracts also are subject to the risks of leveraged transactions, and it may be difficult or impossible for International Opportunities Fund to liquidate an open option contract.

Investments in Other Collective Investment Funds. To the extent that International Opportunities Fund invests in mutual funds and exchange-traded funds (ETFs), its investment performance would be directly related to the investment performance of the other funds. It also would bear its proportionate share of any management and other fees paid by the other funds, subjecting International Opportunities Fund shareholders to some duplication of fees.

Non-Diversification. International Opportunities Fund is "non-diversified," As a result, a decline in the value of the securities of one issuer could have a significant negative effect on International Opportunities Fund.

6

Sector. International Opportunities Fund does not have a policy of investing a significant portion of its assets in any particular industry sector. From time to time, however, it may have significant investments in one or more specific industry sectors, subjecting it to risks of that sector, which may be greater than general market risk.

Regional/Country Focus. International Opportunities Fund does not have a policy of investing a significant portion of its assets in any particular region or country, However, to the extent that International Opportunities Fund focuses its investments in a particular geographic region or country, it may be subject to increased currency, political, regulatory and other risks associated with that region or country.

Cybersecurity and Technology Risk. International Opportunities Fund, its service providers, and other market participants increasingly depend on complex information technology and communications systems, which are subject to different threats and risks that could adversely affect International Opportunities Fund and its shareholders. Cybersecurity and other operational and technology issues may result in financial losses to International Opportunities Fund and its shareholders.
