The Portfolio manager uses credit quality ratings on underlying securities of the portfolio from three major ratings agencies - S&P, Moody's and Fitch. When calculating the credit quality breakdown, the Portfolio manager selects the middle rating of the agencies when all three agencies rate a security. The Portfolio manager will use the lower of the two ratings if only two agencies rate a security and will use one rating if that is all that is provided. Securities that are not rated by any of the three agencies are reflected as not rated.
