Gain on Sale of Assets

Gain on Sale of Assets

During the three months ended June 30, 2018, we sold certain property, plant and equipment for a net gain of approximately $5.1 million as part of our reorganization and consolidation of operations at our headquarters location in Houston, Texas. A gain on property, plant and equipment or intangible assets is calculated as the difference between the cost of the asset disposed of, net of depreciation, and the sales proceeds received. The net gain is reflected in "Gain on sale of assets" line on the Condensed Consolidated Statements of Income.
