Ratings are based on Moody’s Investors Service, Inc. (“Moody’s”), S&P Global Ratings (“S&P”) or Fitch Ratings (“Fitch”), or Kroll Bond Rating Agency, LLC (“Kroll”) for securitized debt instruments only (such as asset-backed and mortgage-backed securities). If securities are rated differently by the ratings agencies, the highest rating is applied. Moody's ratings are converted to the S&P, Fitch and Kroll scale with ratings ranging from AAA, being the highest, to D, being the lowest. Ratings of BBB or higher are considered to be investment-grade quality. Holdings designated as “Not Rated” (if any) are not rated by the national ratings agencies stated above.
