Discontinued Operations and Disposal Groups [Abstract] |
Discontinued Operations | Discontinued Operations During the fourth quarter 2016, the Company initiated a strategic restructuring of its business to enable a greater focus on its core businesses in energy chemistry and consumer and industrial chemistry. The Company executed a plan to sell or otherwise dispose of the Drilling Technologies and Production Technologies segments. An investment banking advisory services firm was engaged and actively marketed these segments. The Company met all of the criteria to classify the Drilling Technologies and Production Technologies segments’ assets and liabilities as held for sale in the fourth quarter 2016. The Company has classified the assets, liabilities, and results of operations for these two segments as “Discontinued Operations” for all periods presented. Disposal of the Drilling Technologies and Production Technologies reporting segments represented a strategic shift that would have a major effect on the Company’s operations and financial results. On December 30, 2016, the Company sold a portion of its Drilling Technologies segment and recorded a loss of $1.2 million which is included in the loss from discontinued operations for the year ended December 31, 2016. On May 22, 2017, the Company completed the sale of substantially all of the assets and transfer of certain specified liabilities and obligations of the Company’s Drilling Technologies segment to National Oilwell Varco, L.P. (“NOV”) for $17.0 million in cash consideration, subject to normal working capital adjustments, with $1.5 million held back by NOV for up to 18 months to satisfy potential indemnification claims. On May 23, 2017, the Company completed the sale of substantially all of the assets and transfer of certain specified liabilities and obligations of the Company’s Production Technologies segment to Raptor Lift Solutions, LLC (“Raptor Lift”) for $2.9 million in cash consideration, with $0.4 million held back by Raptor Lift to satisfy potential indemnification claims. On August 16, 2017, the Company completed the sale of substantially all of the remaining assets of the Company’s Drilling Technologies segment to Galleon Mining Tools, Inc. for $1.0 million in cash consideration and a note receivable of $1.0 million due in one year. The sale or disposal of the assets and transfer or liquidation of liabilities and obligations of these segments was completed in 2017. The Company has no continuing involvement with the discontinued operations.
