The ratings are just normal “slottings”. I doubt you find any A rated subordinated debt. That is the nature of “cap stacks”. Short version, a corporation can issue senior secured, senior unsecured, subordinated, and junior subordinated. Preferreds land on other side of ledger into equity though are often treated as “debt like”.
They generally drop 2 slots per cap stack lowering. That is how rating agencies do it. So if you have a BBB senior unsecured, you pretty much know, if they issued subordinated debt its going to slot BB+. etc. etc. Many times companies will issue subordinated debt because rating agencies will give it 50% “equity credit” for the debt. Conversely preferreds often are given 50% “debt credit”. One gets higher yield here, but the trade off is, if company goes bankrupt you will almost always have your nose pressing against the window on the outside looking in…Along with the preferred and common stock holders.
Added clarity, rating agencies tend to lump preferreds, and subordinated debt together. Thus their 50% debt or equity “credit” given to them. Sometimes they slot a subordinated issue a tick higher. And Fitch sometimes slots a non cumulative preferred a tick lower than a preferred.
Is each bond labeled to designate where it falls in the “Cap Stack” in a consistent and EASY to find way. Or is this something I need to dig out of the prospectus? Thanks
