Disclosure of Long Lived Assets Held-for-sale [Table Text Block]

4. Assets Held for Sale

In the first quarter of 2015, we entered into a plan to sell our two aircraft, and as a result, reclassified the assets from property, plant and equipment to assets held for sale. We also recorded impairment and other charges of $9.8 million, which represents the difference between the carrying value and the estimated fair value and includes a provision for potential settlement of a Texas sales and use tax assessment. We received proceeds, net of selling costs, of $12.2 million for both aircraft in July 2015. As a result, we recorded an additional 1.3 million impairment charge in the second quarter of 2015. As of June 30, 2015, we had current deferred tax liabilities of $2.6 million related to these assets held for sale.
