Asset Disposals | 8. ASSET DISPOSALS During the second quarter of 2016, we sold four light and three medium aircraft and related parts inventory utilized in the Oil and Gas segment. Cash proceeds totaled $10.1 million, resulting in a gain on the sale of these assets of $4.3 million. These aircraft no longer met our strategic needs. During the first quarter of 2016, we sold one light aircraft previously utilized in the Oil and Gas segment. Cash proceeds totaled $0.9 million, resulting in a loss on the sale of this asset of $0.4 million. This aircraft no longer met our strategic needs. There were no sales or disposals of aircraft during the first and second quarter of 2015, but we did have minor sales and disposals of various ancillary equipment.
