Credit Quality Explanation [Text Block]

Credit quality represents a percentage of net assets at the end of the reporting period. Ratings BBB or higher are considered investment grade. Not rated securities do not necessarily indicate low credit quality, and may or may not be equivalent of investment grade. The table reflects Standard & Poor’s (“S&P”) ratings; percentages may include investments not rated by S&P but rated by Moody’s, or if unrated by Moody’s, by Fitch ratings, and then included in the closest equivalent S&P rating. Credit ratings are subject to change. The Fund itself has not been rated by an independent agency.
