The fall in coal prices has caused many mining companies including Walter Energy, Inc. (OTCMKTS:WLTGQ
), Alpha Natural Resources, Inc. (OTCMKTS:ANRZQ
), Patriot Coal Corporation (OTCMKTS:PCXCQ
) and others to file for chapter 11 bankruptcy. Analysts expect that Arch Coal Inc (NYSE:ACI
) may also file for Chapter 11 bankruptcy soon, if it remains unsuccessful in finalizing the credit swap deal this week.
