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 fair value and includes a provision for potential settlement of a Texas sales and use tax assessment. The fair value of assets held for sale of $13.5 million was determined based on the estimated selling price less costs incurred to sell and was classified as Level 2 in the fair value hierarchy. As of March 31, 2015, we had current deferred tax liabilities of $3.0 million related to these assets held for sale.
