The investment seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the Northern Trust Quality Dividend IndexSM. The fund generally will invest under normal circumstances at least 80% of its total assets in the securities of the underlying index. The underlying index is designed to provide exposure to a high-quality, income-oriented portfolio of U.S. equity securities, with an emphasis on long-term capital growth and a targeted overall volatility similar to that of the Northern Trust 1250 IndexSM (the "Parent Index"). It may also invest up to 20% of its assets in cash and cash equivalents.
