Credit Distribution is determined from the highest available credit rating from any Nationally Recognized Statistical Rating Agency (NRSRO”, generally S&P, Moody’s, or Fitch) and is subject to change. DoubleLine chooses to display credit ratings using S&P’s rating convention, although the rating itself might be sourced from another NRSRO. The firm evaluates a bond issuer’s financial strength, or its ability to pay a bond’s principal and interest in a timely fashion. The ratings apply to the credit worthiness of the issuers of the underlying securities and not to the fund itself. Ratings are expressed as letters ranging from ‘AAA’, which is the highest grade, to ‘D’, which is the lowest grade. In limited situations when the rating agency has not issued a formal rating, the rating agency will classify the security as unrated.
