The Fund invests predominantly in common stock. In pursuing these objectives, the investment manager may invest in companies in any economic sector or of any market capitalization both inside and outside of the United States, including emerging markets. The Fund may also invest in depositary receipts. Although the investment manager searches for investments across a large number of sectors, it expects to have significant positions in particular sectors. These sectors may include, for example, technology (including software and internet) and healthcare (including biotechnology). Due to market appreciation, if the market prices of securities held by the Fund rise, the Fund's investment in a sector or the securities of a single company may come to represent a significant portion of the Fund's portfolio. Nevertheless, the investment manager will maintain such a position so long as it believes that the company or sector continues to meet its investment guidelines. The investment manager uses fundamental, "bottom-up" research to seek companies meeting its criteria of growth potential, quality and valuation. In seeking sustainable growth characteristics, the investment manager looks for companies that it believes can produce sustainable earnings and cash flow growth, evaluating the long term market opportunity and competitive structure of an industry to target leaders and emerging leaders. In assessing value, the investment manager considers whether security prices fully reflect the balance of the sustainable growth opportunities relative to business and financial risks. Show less
