DISCONTINUED OPERATIONS

DISCONTINUED OPERATIONS

In December 2013, the Board approved a plan to divest our Natural Gas Storage disposal group. In December 2014, we completed the sale of our Natural Gas Storage disposal group for $102.6 million in cash, net of expenses and working capital adjustments of $2.4 million.  We reported the final working capital adjustments recorded in the first quarter of 2015 as discontinued operations for the year ended December 31, 2015 and we have reported the results of operations for the disposal group as discontinued operations for the years ended December 31, 2014 and 2013. We recorded asset impairment charges of $23.4 million and $169.0 million within “Loss from discontinued operations” on our consolidated statements of operations for the years ended December 31, 2014 and 2013, respectively.  See Note 5 and Note 18 for further discussion.

The following table summarizes the results from discontinued operations (in thousands):
