EXAMPLE. The examples below are intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The examples assume that:

· The Fund’s operating expenses remain the same (except that the examples reflect the expense limitation arrangements for only the first year)

· You reinvest all dividends and distributions

· You pay any deferred sales charge due for the applicable period.

Your actual costs may be higher or lower. Based on these assumptions, for every $10,000 invested, you would pay the following expenses if you sell all of your shares at the end of each time period indicated:

B. Under the heading “SUMMARY SECTION — PRINCIPAL INVESTMENT STRATEGY” in the Prospectus and “PRINCIPAL INVESTMENT STRATEGY” in the Summary Prospectus, the disclosure is deleted and replaced with the following:

The Fund seeks to achieve its investment objective by investing primarily in foreign equity securities. Under normal circumstances, the Fund invests at least 80% of its net assets in equity securities or equity-related securities, including derivative investments that provide exposure to equity securities. The Fund seeks to outperform the MSCI All Country World ex USA Index. The Fund diversifies its investments among a broad range of companies in a number of different countries throughout the world, with no limit on the amount of assets that may be invested in each country. Securities in which the Fund invests are denominated in both U.S. dollars and foreign currencies and may trade in both U.S. and foreign markets. The Fund may invest in securities of companies that conduct their principal business activities in emerging markets or whose securities are traded principally on exchanges in emerging markets. The Fund may invest in companies of any market capitalization, and may trade securities actively.

The Fund employs a multiple sleeve structure, which means the Fund has several components that the sub-adviser, Wellington Management Company LLP (“Wellington Management”), manages using different investment styles. Each component sleeve has a distinct investment philosophy and analytical process to identify specific securities for purchase or sale. With respect to certain sleeves, Wellington Management uses fundamental analysis to select equity securities on the basis of potential for capital appreciation. Wellington Management uses systematic screening methodologies to select equity securities based on their volatility characteristics for other sleeves. Wellington Management does not allocate a set percentage to any specific sleeve but instead seeks a flexible and diversified Fund profile. Together the strategies represent a wide range of investment philosophies, companies, industries, and market capitalizations.

Under normal circumstances, at least 40% (and normally not less than 30%) of the Fund’s net assets will be invested in or exposed to foreign securities or derivative instruments with exposure to foreign securities of at least three different countries outside the United States. Investments are deemed to be “foreign” if: (a) an issuer’s domicile or location of headquarters is in a foreign country; (b) an issuer derives a significant proportion (at least 50%) of its revenues or profits from goods produced or sold, investments made, or services performed in a foreign country or has at least 50% of its assets situated in a foreign country; (c) the principal trading market for a security is located in a foreign country; or (d) they are denominated in a foreign currency. The Fund’s investments in derivative securities, exchange traded funds (ETFs) and exchange traded notes (ETNs) will be considered to be “foreign” if the underlying assets represented by the investment are determined to be foreign using the foregoing criteria.

C. Under the heading “SUMMARY SECTION — MAIN RISKS” in the Prospectus and the heading “MAIN RISKS” in the Summary Prospectus, the following risk is added:

Quantitative Investing Risk - Securities selected using quantitative analysis can perform differently from the market as a whole as a result of the factors used in the analysis, the weight placed on each factor, and changes in the factors’ historical trends.

D. Under the heading “SUMMARY SECTION — MANAGEMENT” in the Prospectus, and “MANAGEMENT” in the Summary Prospectus, the Portfolio Manager table is deleted in its entirety and replaced with the following:

Portfolio Manager	Title	Involved with Fund Since
Kent M. Stahl, CFA	Senior Managing Director and Director, Investments and Risk Management	2010

Gregg R. Thomas, CFA	Senior Managing Director and Director, Risk Management	2013

E. Under the heading “ADDITIONAL INFORMATION REGARDING RISKS AND INVESTMENT STRATEGIES — PRINCIPAL INVESTMENT STRATEGY” in the Prospectus, the disclosure is deleted and replaced with the following:

The Fund seeks to achieve its investment objective by investing primarily in foreign equity securities. Under normal circumstances, the Fund invests at least 80% of its net assets in equity securities or equity-related securities, including derivative investments that provide exposure to equity securities.

Investments are deemed to be “foreign” if: (a) an issuer’s domicile or location of headquarters is in a foreign country; (b) an issuer derives a significant proportion (at least 50%) of its revenues or profits from goods produced or sold, investments made, or services performed in a foreign country or has at least 50% of its assets situated in a foreign country; (c) the principal trading market for a security is located in a foreign country; or (d) they are denominated in a foreign currency. The Fund’s investments in derivative securities, exchange traded funds (ETFs) and exchange traded notes (ETNs) will be considered to be “foreign” if the underlying assets represented by the investment are determined to be foreign using the foregoing criteria.

Wellington Management chooses certain equity securities in which the Fund invests using what is sometimes referred to as a “bottom up” approach, which is the use of fundamental analysis to identify specific securities for purchase or sale. In analyzing a prospective investment, Wellington Management looks at a number of factors, such as business environment, management quality, balance sheet, income statement, anticipated earnings, revenues, dividends and other related measures of valuation and growth potential. Wellington Management also employs systematic screening methodologies to select equity securities based on factors that include, but are not limited, volatility, liquidity, overlap and turnover.

F. Under the heading “ADDITIONAL INFORMATION REGARDING RISKS AND INVESTMENT STRATEGIES — MAIN RISKS” in the Prospectus, the following risk is added:

Quantitative Investing Risk - The value of securities selected using quantitative analysis can react differently to issuer, political, market, and economic developments from the market as a whole or securities selected using only fundamental analysis. The factors used in quantitative analysis and the weight placed on those factors may not be predictive of a security’s value. In addition, factors that affect a security’s value can change over time and these changes may not be reflected in the quantitative model.

G. Under the heading “ADDITIONAL INFORMATION REGARDING RISKS AND INVESTMENT STRATEGIES — Additional Risks and Investment Information” in the Prospectus, the following disclosure is added:

Investment Policies

The Fund has a name which suggests a focus on a particular type of investment. In accordance with Rule 35d-1 under the 1940 Act, the Fund has adopted a policy that it will, under normal circumstances, invest at least 80% of the value of its assets (net assets plus the amount of any borrowings for investment purposes) in investments of the type suggested by its name, as set forth in the Fund’s Principal Investment Strategy section. This requirement is applied at the time the Fund invests its assets. If, subsequent to an investment by the Fund, this requirement is no longer met, the Fund’s future investments will be made in a manner that will bring the Fund into compliance with this requirement. In addition, in appropriate circumstances, synthetic investments may count toward the 80% minimum if they have economic characteristics similar to the other investments included in the basket. The Fund’s policy to invest at least 80% of its assets in such a manner is not a “fundamental” policy, which means that it may be changed without the vote of a majority of the Fund’s outstanding shares as defined in the 1940 Act. The name of the Fund may be changed at any time by a vote of the Fund’s Board of Directors. Shareholders will be given written notice at least 60 days prior to any change by the Fund of its 80% investment policy covered by Rule 35d-1.

H. Under the heading “THE INVESTMENT MANAGER AND SUB-ADVISER — Portfolio Managers” in the Prospectus, the third paragraph and the subsequent portfolio manager information is deleted in its entirety and replaced with the following:

Kent M. Stahl and Gregg R. Thomas serve as the primary portfolio managers of the Fund and select and oversee the Fund’s portfolio management personnel and determine how Fund assets are allocated among the management teams. Allocations among teams are made using both qualitative and quantitative factors. Quantitative considerations include the use of proprietary and third-party risk models to assess exposures, including those to risk factors (including volatility), market cap, and style. The selection and allocation process is ongoing with monitoring and formal reviews conducted on a regular basis. Qualitative inputs include team’s style, conviction, and clarity of philosophy and process. Generally, a 3-5 year view is used when making allocation decisions for the portfolio; however, there are no specific requirements about how often an allocation or a portfolio management team is changed. Changes may be made at any time based on market conditions and/or Fund performance. Each portfolio management team is responsible for managing the portion of the Fund allocated to it by Messrs. Stahl and Thomas (“Sleeve”). The Sleeves are managed independently of each other and each portfolio management team has full discretion to manage its Sleeve.

Kent M. Stahl, CFA, Senior Managing Director and Director of Investments and Risk Management of Wellington Management, has been involved in portfolio management for the Fund since 2010 and oversees the allocation of assets among the Fund’s broad strategies and corresponding portfolio manager approaches. Mr. Stahl joined Wellington Management as an investment professional in 1998.

Gregg R. Thomas, CFA, Senior Managing Director and Director of Risk Management of Wellington Management, has been involved in portfolio management and securities analysis for the Fund since 2013. Mr. Thomas joined Wellington Management in 2001 and has been an investment professional since 2004.

I. Under the heading “THE INVESTMENT MANAGER AND SUB-ADVISER — MANAGEMENT FEE” in the Prospectus, the second paragraph is deleted and replaced with the following:

Effective August 13, 2015, the management fee set forth in the Fund’s investment advisory agreement is 0.70% of the first $500 million, 0.65% of the next $500 million, 0.64% of the next $1.5 billion, 0.63% of the next $2.5 billion, and 0.625% in excess of $5 billion annually of the Fund’s average daily net assets. The Investment Manager pays a sub-advisory fee to Wellington Management out of its advisory fee.

Prior to August 13, 2015, the management fee set forth in the Fund’s investment advisory agreement was 0.900% of the first $500 million, 0.850% of the next $4.5 billion, 0.8475% of the next $5 billion and 0.8450% in excess of $10 billion annually of the Fund’s average daily net assets.
