Credit quality ratings on underlying securities of the fund are received from S&P, Moody’s and Fitch and converted to the equivalent S&P major rating category. This breakdown is provided by Azimuth and takes the median rating of the three agencies when all three agencies rate a security. When not rated by all three agencies, Bloomberg Composite will be used. Unrated securities do not necessarily indicate low quality. Below investment-grade is represented by a rating of BB and below. Ratings and portfolio credit quality may change over time.
