The Fund may invest up to 100% of its net assets in dividend-paying equities of companies of any size large, medium and small. Additionally, the Fund may also invest up to 100% of its assets in foreign debt and/or depositary receipts. The Funds investments in any one sector may exceed 25% of its net assets. The Funds allocation among various fixed income securities is based on the portfolio managers assessment of opportunities for total return relative to the risk of each type of investment. The Adviser may sell a security when it believes doing so is appropriate and consistent with the Funds investment objectives and policies or when conditions affecting relevant markets, particular industries or individual issues warrant such action, regardless of the effect on the Funds portfolio turnover rate.
