Credit quality ratings shown reflect the ratings assigned by Moody’s Investors Service (“Moody’s”), a widely used independent, nationally recognized statistical rating organization. Moody’s credit ratings are opinions of the credit quality of individual obligations or of an issuer’s general creditworthiness. Investment grade ratings are credit ratings of Baa or higher. Below investment grade ratings are credit ratings of Ba or lower. Unrated investments do not necessarily indicate low credit quality. Credit quality ratings are subject to change. |
