Strategy Narrative [Text Block]	The fund is an exchange-traded fund (ETF), which is a fund that trades like other publicly-traded securities. The fund is not an index fund. The fund is actively managed and does not seek to replicate the performance of a specified index. Under normal market conditions, the fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in a portfolio of equity and equity-related securities issued by non-U.S. large and mid-capitalization companies that meet the fund’s value criteria. The fund may invest in all types of equity and equity-related securities, including, without limitation, exchange-traded and over-the-counter common and preferred stocks, warrants, options, rights, convertible securities, sponsored and unsponsored depositary receipts and shares, trust certificates, participatory notes, limited partnership interests, shares of other investment companies (including exchange-traded funds (ETFs)), real estate investment trusts (REITs), and equity participations. Equity participations are loans that give the lender a portion of equity ownership in a property, in addition to principal and interest payments. A convertible security is a bond, debenture, note, preferred stock, or other security that may be converted into or exchanged for a prescribed amount of common stock of the same or a different issuer within a particular period of time at a specified price or formula. The fund defines non-U.S. companies as companies: (i) that are organized under the laws of a foreign country; (ii) whose principal trading market is in a foreign country; or (iii) that have a majority of their assets, or that derive a majority of their revenue or profits, from businesses, investments, or sales outside of the United States. The fund’s non-U.S. investments, which may be denominated in U.S. or foreign currencies, primarily focus on developed markets, but may include emerging- and frontier-market investments. The fund defines large and mid-capitalization as those companies with a market capitalization over $250 million. The fund generally invests in the equity securities of issuers the manager believes are undervalued. The manager applies a bottom-up stock selection process using a combination of fundamental and quantitative analysis of issuer-specific factors such as price-to-book value, price-to-sales and earnings ratios, dividend yields, strength of management, and cash flow. The fund may invest in derivatives. Derivatives may be used to reduce risk, obtain efficient market exposure, and/or enhance investment returns, and may include put and call options, futures, forward contracts, and swaps. The fund may invest up to 15% of its net assets in illiquid securities and may participate as a purchaser in Initial Public Offerings (IPOs). The fund may also seek to increase its income by lending portfolio securities. Due to the nature of certain of the fund’s investments, the fund may, under certain circumstances, effect a portion or all of creations and redemptions for cash, rather than in-kind securities. The fund is non-diversified, which means that it may invest in a smaller number of issuers than a diversified fund and may invest more of its assets in the securities of a single issuer.
