Under typical market conditions, at least 70% of the fund's portfolio must consist of debt instruments that, at the time of purchase, are either assigned an investment-grade rating by a nationally recognized statistical rating organization (NRSRO) or are judged by the adviser to be of comparable quality despite lacking an official rating. Conversely, the fund will limit its exposure to below-investment-grade securities (or their unrated equivalents) to a maximum of 30% of its net assets during normal circumstances. Additionally, up to 25% of the portfolio's net assets can be invested in foreign-issued debt, which includes obligations from sovereign nations and their agencies.
