The investment seeks to maximize total return (capital appreciation and income), adjusted for the federal maximum tax rate, to the extent consistent with preservation of principal. The fund will, under normal circumstances, invest primarily (and not less than 80% of its net assets) in fixed-income securities. It invests in investment grade domestic debt obligations (i.e., obligations rated within the top four rating categories by a Nationally Recognized Statistical Rating Organization ("NRSRO") or of comparable quality as determined by the fund's investment adviser).
