Coal producer Patriot Coal Corp. on Tuesday reported decline in net income for the fourth quarter mainly due to restructuring and impairment charges. Revenues in the 2009 fourth quarter dropped to $503.2 million, compared to $506.2 million in third quarter due to lower tons sold, partially offset by higher average selling prices.

Revenues for 2009 increased $390.7 million compared to 2008, primarily due to the inclusion of a full year of Magnum results, partially offset by lower thermal coal volume in 2009. Revenues in the 2009 fourth quarter were $37.9.
