Strategy [Heading]	Principal Strategies
Strategy Narrative [Text Block]	The Fund invests primarily in the equity securities of foreign and domestic companies. Under normal market conditions, we will invest the Fund’s net assets primarily in the equity securities, typically common stock, of foreign and domestic companies of all market capitalizations. The Fund will typically invest in securities issued by companies domiciled in at least three countries, including the United States. The Fund will invest a significant portion of its total assets in companies domiciled in foreign countries (under normal market conditions, we expect at least 40% of its assets to be invested outside the United States, or if conditions are not favorable, 30% of its assets to be invested outside the United States). Securities issued by foreign companies incorporated outside the United States whose securities are principally traded in the United States are not defined as “foreign companies” and are not subject to this limitation. The Fund may invest a significant amount of its total assets (5% to 50% under normal market conditions) at the time of purchase in securities issued by companies domiciled in emerging and frontier markets, which are those countries currently included in the Morgan Stanley Capital International (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. The Fund may invest in the equity securities of companies of any size, although we expect a significant portion of the Fund’s assets to be invested in companies with market capitalizations of over $5 billion at the time of purchase. To achieve the Fund’s investment objectives, the Fund invests in securities that we believe are priced below their intrinsic long-term value based on our valuation analysis. When evaluating a potential investment for the Fund, we employ a comprehensive valuation analysis intended to establish a range for fair valuation or intrinsic company value, with a particular emphasis on company fundamentals. The initial valuation review may include: • Calculating and reviewing standard ratios, such as price-to-sales, price-to-book, price-to-earnings, and price/earnings-to-growth. • Discounted cash flow models with sensitivity analysis for changes to revenue growth rates, operating margins, outstanding share counts, earnings multiples, and tangible book value. The Fund typically seeks to sell a security when the issuing company becomes overvalued relative to our analysis of its intrinsic long-term value. The Fund may invest a significant amount of its assets (greater than 5%) in a particular region or market, including Asia and Europe. The Fund may invest a large percentage of its assets (greater than 5%) in a few sectors. As of the date of this Prospectus, these sectors were financials, health care, utilities, energy, consumer staples, information technology, communication services, industrials, materials, and real estate.
