(a)

The deferred sales charge is imposed on Class C Shares redeemed during the first year only.

(b)

The fund’s investment adviser has contractually agreed to limit the fund’s total operating expenses (excluding certain expenses, such as front-end or contingent deferred sales charges, taxes, leverage and borrowing expenses (such as commitment, amendment and renewal expenses on credit or redemption facilities), interest, brokerage commissions, expenses incurred in connection with any merger or reorganization, unusual or infrequently occurring expenses (such as litigation), acquired fund fees and expenses, and dividend expenses, if any) so that such expenses do not exceed 1.36% for Class A Shares, 2.11% for Class C Shares, 1.09% for Class I Shares and 0.90% for Class R6 Shares through March 31, 2021. Following the contractual period, the adviser may discontinue these expense reimbursement arrangements at any time. Under certain conditions, the adviser may recapture operating expenses reimbursed and/or fees waived under these arrangements for a period of three years following the date such waiver or reimbursement occurred, provided that the recapture does not cause the fund to exceed its expense limit in effect at the time of the waiver or reimbursement, or at the time of recapture.

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 that 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 or continued to hold them. The example also assumes that your investment has a 5% return each year, that the fund’s operating expenses remain the same and that the expense reimbursement agreement remains in place for the contractual period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

​	Share Status	1 Year		3 Years		5 Years		10 Years
Class A	Sold or Held	​	$706	​	$985	​	$1,289	​	$2,151
Class C	Sold	​	$314	​	$666	​	$1,150	​	$2,485
	Held	​	$214	​	$666	​	$1,150	​	$2,485
Class I	Sold or Held	​	$111	​	$355	​	$628	​	$1,406
Class R6	Sold or Held	​	$92	​	$307	​	$560	​	$1,284

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 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 35% of the average value of its portfolio.

Investments, Risks and Performance

Principal Investment Strategies

This fund seeks to provide investors with exposure to high-quality global companies. The securities selected for inclusion in the fund are those believed by the subadviser to be well-managed businesses with consistent operating histories and financial performance that have favorable long-term economic prospects and, in most cases, generate free cash flow. Over full market cycles, the investment style is designed with the objective of capturing part of the up market cycles and may offer protection in down market cycles.

Under normal circumstances, the fund invests in equity securities or equity-linked instruments of issuers located throughout the world, including issuers in emerging markets countries and issuers in the United States. The fund intends to diversify its investments among countries and normally to have represented in the portfolio business activities of a number of different countries. In determining “location” of an issuer, the subadviser primarily relies on the country where the issuer is incorporated. However, the country of risk is ultimately determined based on analysis of the following criteria: actual building address (domicile), primary exchange on which the security is traded and country in which the greatest percentage of company revenue is generated. This evaluation is conducted so as to determine that the issuer’s assets are exposed to the economic fortunes and risks of the designated country.

Principal Risks

The fund may not achieve its objective(s), and it is not intended to be a complete investment program. The value of the fund’s investments that supports your share value may decrease. If between the time you purchase shares and the time you sell shares the value of the fund’s investments decreases, you will lose money. Investment values can decrease for a number of reasons. Conditions affecting the overall economy, specific industries or companies in which the fund invests can be worse than expected, and investments may fail to perform as the subadviser expects. As a result, the value of your shares may decrease. Purchase and redemption activities by fund shareholders may impact the management of the fund and its ability to achieve its investment objective(s). The principal risks of investing in the fund are identified below.

>

Equity Securities Risk.  The value of the stocks held by the fund may be negatively affected by the financial market, industries in which the fund invests, or issuer-specific events. Focus on a particular style or in small or medium-sized companies may enhance that risk.

>

Foreign Investing Risk.  Investing in foreign securities subjects the fund to additional risks such as increased volatility; currency fluctuations; less liquidity; and political, regulatory, economic, and market risk.

>

Emerging Market Risk.  Emerging markets securities may be more volatile, or more greatly affected by negative conditions, than those of their counterparts in more established foreign markets.

>

Equity-Linked Instruments Risk.  The fund’s value may be negatively affected by factors relating to the risks of the referenced equity security, and the fund may experience a return different than the referenced equity security. Equity-linked instruments expose the fund to counterparty risk, which could result in a loss of all or part of the fund’s investment.

>

Market Volatility Risk.  The value of the securities in the fund may go up or down in response to the prospects of individual companies and/or general economic conditions. Price changes may be short- or long-term.

>

Redemption Risk.  One or more large shareholders or groups of shareholders may redeem their holdings in the fund, resulting in an adverse impact on remaining shareholders in the fund by causing the fund to take actions it would not otherwise have taken.
