Fees and Expenses of the Fund

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

Shareholder Fees (fees paid directly from your investment)	Institutional Class Shares
Maximum Sales Charge (Load) Imposed on Purchases (as a % of offering price)	None
Redemption Fee (as a % of amount redeemed on shares held 60 days or less)	2.00%

Wasatch Advisors, Inc. (Advisor), the Fund’s investment advisor, has contractually agreed to reimburse the Institutional Class shares of the Fund for Total Annual Fund Operating Expenses in excess of 1.35% of average daily net assets until at least January 31, 2018 (excluding interest, dividend expense on short sales/interest expense, taxes, brokerage commissions, other investment related costs, acquired fund fees and expenses, and extraordinary expenses, such as litigation and other expenses not incurred in the ordinary course of business). The Board of Trustees is the only party that can terminate the contractual limitation prior to the contract’s expiration. The Advisor can rescind the contractual limitation on expenses at any time after its expiration date.

Example

This example is intended to help you compare the cost of investing in the Institutional Class of the Fund with the cost of investing in other mutual funds. The example assumes that you invested $10,000 in the Institutional 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 operating expenses (as a percentage of net assets) of the Fund’s Institutional Class remained the same. This example reflects contractual fee waivers and reimbursements through January 31, 2018. 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 Growth Fund — Institutional Class	$137	$430	$744	$1,635

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 50% of the average value of its portfolio.

Principal Strategies

The Fund invests primarily in foreign growth companies.

Under normal market conditions, we will invest the Fund’s assets in the equity securities of foreign companies with market capitalizations of less than US$5 billion at the time of purchase. Equity securities include common stock, preferred stock and securities convertible into common stock, warrants and rights, and other securities with equity characteristics (for example, participatory notes or derivatives linked to a basket of underlying equity securities, certain options on common stock, and exchange-traded funds). 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 (5% to 70% under normal market conditions) at the time of purchase in securities issued by companies domiciled in emerging markets. The Fund defines emerging market countries as 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 consumer discretionary, consumer staples, financials, health care, industrials, information technology and materials.

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. An investment in the Fund is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.

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’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 investments in U.S. securities. 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, can have a significant effect on the value of a foreign security. Additionally, certain countries may utilize formal or informal currency-exchange controls or “capital controls.” Capital controls may impose restrictions on the Fund’s ability to repatriate investments or income. Such capital controls can also have a significant effect on the value of the Fund’s holdings.

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.

Small Company Stock Risk. Small-cap stocks may be very sensitive to changing economic conditions and market downturns because the issuers often have narrow markets for their products or services, fewer product lines, and more limited managerial and financial resources than larger issuers. The stocks of small-cap companies may therefore be more volatile and the ability to sell these stocks at a desirable time or price may be more limited.

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

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.

Sector Weightings Risk. To the extent the Fund emphasizes, from time to time, investments in a particular sector, the Fund will be subject to a greater degree to the risks particular to that sector, including the sectors described below. 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 securities in those sectors.

Consumer Discretionary Sector Risk. Industries in the consumer discretionary sector, such as consumer durables, hotels, restaurants, media, retailing, and automobiles, may be significantly impacted by the performance of the overall economy, interest rates, competition, consumer confidence and spending, and changes in demographics and consumer tastes.

Consumer Staples Sector Risk. The consumer staples sector may be affected by marketing campaigns, changes in consumer demands, government regulations and changes in commodity prices.

Financials Sector Risk. The financials sector is subject to extensive government regulation, can be subject to relatively rapid change due to increasingly blurred distinctions between service segments, and can be significantly affected by the availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, and price competition.

Health Care Sector Risk. Health care companies are strongly affected by worldwide scientific or technological developments. Their products may rapidly become obsolete. Many health care companies are also subject to significant government regulation and may be affected by changes in government policies.

Industrials Sector Risk. Industries in the industrials sector include companies engaged in the production, distribution or service of products or equipment for manufacturing, agriculture, forestry, mining, and construction, and can be significantly affected by general economic trends, including such factors as employment and economic growth, interest rate changes, changes in consumer spending, legislative and government regulation and spending, import controls, commodity prices, and worldwide competition.

Information Technology Sector Risk. Stocks of information technology companies may be volatile because issuers are sensitive to rapid obsolescence of existing technology, short product cycles, falling prices and profits, competition from new market entrants, and general economic conditions. Information technology stocks, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market.

Materials Sector Risk. Changes in world events, political, environmental and economic conditions, energy conservation, environmental policies, commodity price volatility, changes in currency exchange rates, imposition of import controls, increased competition, depletion of resources, and labor relations may adversely affect companies engaged in the production and distribution of materials.

Historical Performance

The Institutional Class is new and does not have a full calendar year of performance. The following tables provide information on how the Investor Class shares of the Fund have performed over time. The calendar year returns in the bar chart, the best and worst quarterly returns and the average annual total returns table are based on the Fund’s Investor Class shares. Investor Class shares are not offered in this Prospectus. Performance for Investor Class shares would be similar to that for Institutional Class shares because the shares are invested in the same portfolio of securities and would differ only to the extent that Institutional Class shares have different expenses. The past performance, before and after taxes, is not necessarily an indication of how these shares will perform in the future. The bar chart below is intended to provide you with an indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year, as represented by the Investor Class of the Fund. The table below is designed to help you evaluate your risk tolerance by showing the Fund’s best and worst quarterly performance for the years shown in the bar chart. The average annual total returns table below allows you to compare the Fund’s performance over the time periods indicated to that of a broad-based market index and an additional index composed of securities similar to those held by the Fund. Performance information is updated regularly and is available on the Fund’s website www.WasatchFunds.com.

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. You will generally have to pay federal income taxes, and any applicable state or local taxes, on the distributions you receive from the Fund as ordinary income or capital gains unless you are investing through a tax exempt account such as a qualified retirement plan. Distributions on investments made through tax-deferred vehicles, such as 401(k) plans or IRAs, may be taxed later upon withdrawal of assets from those plans or accounts.

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 or 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.
