SUBSEQUENT EVENT:

On October 25, 2013, CONSOL Energy entered into an agreement to sell Consolidation Coal Company (CCC) and certain of its subsidiaries, which contains all five of its longwall coal mines in West Virginia, to a subsidiary of Murray Energy Corporation (Murray Energy).  The CCC mines being sold are McElroy Mine, Shoemaker Mine, Robinson Run Mine, Loveridge Mine, and Blacksville No. 2 Mine. Collectively, these mines produced 28.5 million tons of thermal coal in 2012. Murray Energy is acquiring approximately 1.1 billion tons of Pittsburgh No. 8 seam reserves. CONSOL Energy’s River and Dock Operations are included in the transaction. In 2012, the fleet of 21 towboats and 600 barges transported 19.3 million tons of coal and other commodities along the upper Ohio River system. CONSOL Energy will receive $850,000 in cash as a result of the transaction and in addition Murray Energy will assume certain employee and environmental related liabilities with a book value of approximately $2,400,000 at September 30, 2013. The final financial gain will be calculated upon closing, which is expected to occur during the fourth quarter.
