Ferrellgas Partners, L.P. (NYSE: FGP) cut its distribution last year — not a good thing for income investors. Today it yields around 6.7%, lofty on an absolute basis but nowhere near Suburban Propane Partners‘ (NYSE: SPH) 14% distribution yield. There’s a lot more to understand here, however, and in this case, the bad news from Ferrellgas might actually make it the safer investment option.
