Yup, I just see buyouts and typically...5-10% of enterprise value.  I the case of PRB grades will put it into the 450-650 million "max"4-5%.  10% with great grades is around 1.1 billion.

Eldorado just closed 500,000,000 U.S. in senior notes ( payed a little debt down ).  I think they are most likely to merge/buy PRB
