|----------------------------------------------------------------------------------------------------------------------|
| Management Fees (vary with performance)                                                                              | 0.61% |

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 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 operating expenses remain the same. Although actual costs may be higher or lower, based on these assumptions, your costs would be:

| 1 year | 3 years | 5 years | 10 years |
|--------|---------|---------|----------|
| $107   | $334    | $579    | $1,283   |

Portfolio Turnover

The Fund may have transaction costs, such as commissions and a bid-ask spread,  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 0.00% of the average value of its portfolio.

### Principal Investment Strategies

The International Fund diversifies its investments among many countries, predominantly those with mature markets (such as Europe and Canada). The Fund invests at least 65% of its assets in companies with their headquarters and major assets and earnings outside the US. The Fund diversifies its investments across industries, companies, and countries. The Fund looks for companies with growing revenues and earnings, favoring companies trading for less than the adviser's assessment of intrinsic value, which typically means companies with low price/earning multiples, low price to cash flow, and higher dividend yields. There is no restriction on the size of companies in which the Fund invests, but it principally invests in larger and more established firms.

### Principal Risks of Investing

**Market risk:** The value of the Fund's shares rises and falls as the market value of the securities in which the Fund invests goes up and down. The market value of securities will fluctuate, sometimes significantly and unpredictably, with stocks generally being more volatile than bonds. When you redeem your shares, they may be worth more or less than what you paid for them. Only consider investing in the Fund if you are willing to accept the risk that you may lose money.

**Equity securities risk:** Equity securities may experience significant volatility in response to economic or market conditions or adverse events that affect a particular industry, sector, or company. Although the Fund may invest in companies of all sizes, the Fund tends to favor larger companies and, to a lesser extent, midsize companies. Larger companies may have slower rates of growth as compared to smaller, faster-growing companies. Midsize companies may have more limited financial resources, products, or services, and tend to be more sensitive to changing economic or market conditions.

**Foreign investing risk:** Foreign investing involves risks not normally associated with US securities. These risks include fluctuations in currency exchange rates, less public information about securities, less governmental market supervision, and lack of uniform financial, social, and political standards. Foreign investing heightens the risk of confiscatory taxation, seizure or nationalization of assets, currency controls, or adverse political or social developments that affect investments.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates but do not reflect the impact of any state or local taxes. Actual after-tax returns depend on an investor's tax situation and likely differ from those shown. After-tax illustrations are not relevant to retirement plans, corporations, trusts, or other investors that are taxed at special rates.

In loss periods, the average after-tax total return may be higher than average annual total return because of an assumed deduction of losses from other income.

### Financial Intermediary Compensation

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and its related companies may pay the intermediary for the sale of Fund shares and related services.

Ask your salesperson or visit your financial intermediary's website for more information.
