I am interested in buying a commercial bond issued by a coal mining company. The CUSIP is
62704PAM5. I searched online at tdameritrade.com and was not able to find the bond using their bond search tool. I called in to the fixed income department at TD Ameritrade and they were not able to find it either.
Is there a reason a commercial bond like the one I referenced above wouldn't be available through a major broker? The issuer, Murray Energy, is a top 5 coal producer in the United States and is rated by the major credit agencies.
