Divestiture of Properties

  In total, the Company has divested a number of non-core assets for total net proceeds of $30.7 million from 2015 to 2017.  No gain or loss was recognized during 2015, 2016 or 2017 upon the sale or disposition of oil and gas properties since the adjustment to the full cost pool did not result in a significant alteration of the relationship between capitalized cost and proved reserves.

In July 2017, the Company closed on the divestiture of a portion of its Powder River Basin assets for approximately $4.6 million. No gain or loss was recognized on this transaction.
