Expense Example $

The Example is intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example show costs if you sold (redeemed) your shares at the end of the period or continued to hold them. The Examples also assumes that your investment had a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Class	Share Status		1 Yr	3 Yrs	5 Yrs	10 Yrs
I	Sold or Held	$	100	312	542	1,201

The Example reflects applicable expense limitation agreements and/or waivers in effect, if any, for the one-year period and the first year of the three-, five-, and ten-year periods.

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 mean higher taxes if you are investing in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Expense Example, affect the Fund's performance.

During the most recent fiscal year, the Fund's portfolio turnover rate was 48% of the average value of its portfolio.

in emerging markets. The Fund does not focus its investments in a particular industry or country. The Fund may invest in companies of any market capitalization. The equity securities in which the Fund may invest include, but are not limited to, common stocks, preferred stocks, depositary receipts, rights and warrants to buy common stocks, and privately placed securities. The Fund may invest in derivative instruments including options, futures, and forward foreign currency exchange contracts. The Fund may typically use derivatives to seek to reduce exposure to other risks, such as interest rate or currency risk, to substitute for taking a position in the underlying assets, for cash management, and/or to seek to enhance returns in the Fund.

The Fund invests its assets in foreign investments which are denominated in U.S. dollars, major reserve currencies and currencies of other countries and can be affected by fluctuations in exchange rates. To attempt to protect against adverse changes in currency exchange rates, the Fund may, but will not necessarily use special techniques such as forward foreign currency exchange contracts.

The Fund may invest in other investment companies, including exchange traded funds, to the extent permitted under the Investment Company Act of 1940, as amended, and the rules, regulations, and exemptive orders thereunder (“1940 Act”).

Baillie Gifford Overseas Limited (“Baillie Gifford”), J.P. Morgan Investment Management Inc. (“JPMorgan”), Lazard Asset Management LLC (“Lazard”), and T. Rowe Price Associates, Inc. (“T. Rowe Price”) (each a “Sub-Adviser” and collectively “Sub-Advisers”) provide day-to-day management of the Fund. The Sub-Advisers act independently of each other and use their own methodologies for selecting investments. The Fund's investment adviser will determine the amount of Fund assets allocated to each Sub-Adviser.

Each Sub-Adviser may sell securities for a variety of reasons, such as to secure gains, limit losses, or redeploy assets into opportunities believed to be more promising, among others.

The Fund may lend portfolio securities on a short-term or long-term basis, up to 33  ¹ ∕ 3 % of its total assets.

Baillie Gifford Overseas Limited

In selecting investments for the Fund, Baillie Gifford normally takes into account the industry and country allocations in the MSCI EAFE ^® Index. A significant part of the assets will normally be divided among continental Europe, the United Kingdom, and Asia (including Australia and New Zealand). Country allocation, however, is driven by stock selection. Baillie Gifford invests in companies that it believes are well-managed, quality businesses that enjoy sustainable, competitive advantages in their marketplace. Baillie Gifford's investment style primarily uses a bottom-up, stock-driven approach, with the objective of selecting stocks that it believes can sustain an above-average growth rate, which is not reflected in the share price.

Companies are screened for quality first; valuation is a secondary consideration. Baillie Gifford looks for companies that it believes have attractive industry backgrounds, strong competitive positions within those industries, high-quality earnings, and a positive approach toward shareholders. The main fundamental factors that Baillie Gifford considers in this bottom-up analysis include earnings growth, cash flow growth, profitability, capital structure, and valuation.

J.P. Morgan Investment Management Inc.

In choosing securities, JPMorgan seeks to provide high total return by investing primarily in equity securities from developed countries included in the MSCI EAFE ^® Value Index while emphasizing securities that are ranked as undervalued according to its proprietary research while underweighting or avoiding those that appear over-valued. JPMorgan employs a process that combines fundamental research for identifying portfolio securities and currency management decisions. Various models are used to quantify JPMorgan’s fundamental stock research, producing a ranking of companies in each industry group according to their relative value. JPMorgan then buys and sells securities, using the research and valuation rankings as well as its assessment of other factors, including: (i) value characteristics such as low price-to-book and price-to-earnings ratios; (ii) catalysts that could trigger a change in a stock’s price; (iii) potential reward compared to potential risk; and (iv) temporary mispricings caused by market overreactions.

Lazard Asset Management LLC

In choosing securities, Lazard normally invests in large non-U.S. companies with market capitalizations in the range of companies included in the MSCI EAFE ^® Index that Lazard believes are undervalued based on their earnings, cash flow or asset values. Lazard looks for established companies in economically developed countries and may invest in securities of companies whose principal business activities are located in emerging market countries.

T. Rowe Price Associates, Inc.

While T. Rowe Price invests with an awareness of the global economic backdrop and the outlook for industry sectors and individual countries, bottom-up stock selection is the focus of T. Rowe Price's decision making. Country allocation is driven largely by stock selection, though we may limit investments in markets that appear to have poor overall prospects.

Securities selection reflects a growth style. T. Rowe Price relies on a global team of investment analysts dedicated to in-depth fundamental research in an effort to identify companies it believes are capable of achieving and sustaining above-average, long-term earnings growth. T. Rowe Price seeks to purchase stocks of such companies at reasonable prices in relation to present or anticipated earnings, cash flow, or book value.

In selecting investments, T. Rowe Price generally favors companies that it believes have one or more of the following characteristics: leading or improving market position; attractive business niche;

attractive or improving franchise or industry position; seasoned management; stable or improving earnings and/or cash flow; and sound or improving balance sheet.

T. Rowe Price typically focuses investments in large-sized, and to a lesser extent, medium-sized, companies.

established secondary market may make it more difficult to value illiquid securities, which could vary from the amount the Fund could realize upon disposition. The Fund may make investments that become less liquid in response to market developments or adverse investor perception. The Fund could lose money if it cannot sell a security at the time and price that would be most beneficial to the Fund.

Market     Stock prices may be volatile and are affected by the real or perceived impacts of such factors as economic conditions and political events. Stock markets tend to be cyclical, with periods when stock prices generally rise and periods when stock prices generally decline. Any given stock market segment may remain out of favor with investors for a short or long period of time, and stocks as an asset class may underperform bonds or other asset classes during some periods. From time to time, the stock market may not favor the growth- or value-oriented securities in which the Fund invests. Rather, the market could favor securities to which the Fund is not exposed or may not favor equities at all. Additionally, legislative, regulatory or tax policies or developments in these areas may adversely impact the investment techniques available to a manager, add to Fund costs and impair the ability of the Fund to achieve its investment objectives.

Market Capitalization     Stocks fall into three broad market capitalization categories - large, mid, and small. Investing primarily in one category carries the risk that, due to current market conditions, that category may be out of favor with investors. If valuations of large-capitalization companies appear to be greatly out of proportion to the valuations of mid- or small-capitalization companies, investors may migrate to the stocks of mid- and small-sized companies causing the Fund that invests in these companies to increase in value more rapidly than a fund that invests in larger, fully-valued companies. Investing in mid- and small-capitalization companies may be subject to special risks associated with narrower product lines, more limited financial resources, smaller management groups, and a more limited trading market for their stocks as compared with larger companies. As a result, stocks of mid- and small-capitalization companies may decline significantly in market downturns.

Other Investment Companies     The main risk of investing in other investment companies, including exchange-traded funds, is the risk that the value of the securities underlying an investment company might decrease. Because the Fund may invest in other investment companies, you will pay a proportionate share of the expenses of those other investment companies (including management fees, administration fees, and custodial fees) in addition to the expenses of the Fund.

Securities Lending     Securities lending involves two primary risks: “investment risk” and “borrower default risk.” Investment risk is the risk that the Fund will lose money from the investment of the cash collateral received from the borrower. Borrower default risk is the risk that the Fund will lose money due to the failure of a borrower to return a borrowed security in a timely manner.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

investors who hold their Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts. In some cases the after-tax returns may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period.

TAX INFORMATION

The Fund's distributions are generally taxable to you as ordinary income, capital gains, or a combination of the two, unless you are investing through a tax-deferred arrangement, such as a 401(k) plan or an individual retirement account. If you are investing through a tax-deferred arrangement, you may be taxed upon withdrawals from that arrangement.
