I think you didn't get the memo. Yes there is going to be a dividend decrease. Witness: News from Dow Jones on 10/31...
Rhino Resource Partners Sees FY Cash Available for Distribution $43M-$47M
Based on their shares outstanding of about 29 million, then dividend should be around 43/29 = $1.48.
Still about 15% based on current pricing, so I'm sort of scratching my head here as to why RNO is trading this low. Perhaps it's end of year tax loss selling.
