Office Closing and Exit Activities [Abstract]  
OFFICE CLOSING AND EXIT ACTIVITIES
     
(19)   OFFICE CLOSING AND EXIT ACTIVITIES
     In February 2010, we entered into an agreement to sell our natural gas properties in Ohio. We closed approximately 90% of the sale in March 2010 and closed the remainder of the sale in June 2010. The first quarter 2010 includes $5.1 million accrued severance costs, which is reflected in termination costs in the accompanying consolidated statements of operations. As part of their severance agreement, our Ohio employees’ vesting of SARs and restricted stock grants was accelerated, increasing termination costs for stock compensation expense in first quarter 2010 by approximately $2.8 million.
     The following table details our exit activities, which are included in accrued liabilities in the accompanying consolidated balance sheets as of June 30, 2011 and December 31, 2010 (in thousands):
