Description Of Business	Description of Business CIRCOR International, Inc. (“CIRCOR” or the “Company” or “we”) designs, manufactures and distributes a broad array of flow and motion control products and certain services to a variety of end-markets for use in a wide range of applications to optimize the efficiency and/or ensure the safety of flow control systems. We have a global presence and operate major manufacturing facilities in North America, Western Europe, Morocco, and India. As of December 31, 2019, we organized our business segment reporting structure into three segments: CIRCOR Energy ("Energy"), CIRCOR Aerospace and Defense ("Aerospace and Defense") and CIRCOR Industrial ("Industrial"). Refer to Note 19, Business Segment and Geographical Information, for further information about our segments. During 2018 and 2019, the Company entered into several significant transactions as described below. In November 2018, the Company sold its Rosscor B.V. and SES International B.V. subsidiaries (the “Delden Business”) for a nominal amount. The Delden Business was our Netherlands-based fluid handling skids and systems business, primarily for the oil and gas end market. We maintain a 19.9% interest in the Delden Business, as well as the intellectual property rights to our two-screw pump product line. The Company determined that the accounting for this transaction is not material to our consolidated financial statements. In January 2019, the Company sold its Reliability Services ("RS") business for approximately $85 million in cash, on a cash-free, debt-free basis, subject to working capital and other adjustments of approximately $(5) million. The RS business provided lubrication management, chemical flushing services, and oil misting equipment to the oil and gas industry. The RS business was acquired as part of the acquisition of the Colfax Fluid Handling (“FH”) business, which is described further in Note 5, Business Acquisitions. The disposal group did not meet the criteria to be classified as discontinued operations. However, it did meet the criteria for presentation as held for sale. Accordingly, the RS assets and liabilities were collapsed as held for sale within our consolidated balance sheet at December 31, 2018. In July 2019, the Company sold its Engineered Valves ("EV") business for a nominal amount, with an earnout of 50% of net income over seven years up to a maximum of $20.6 million (€18 million). The EV business is a long-cycle upstream oil and gas engineered value business. The disposal group met the criteria to be classified as discontinued operations, and is recorded as such within our consolidated financial statements. All prior period comparative financial information has been reclassified to conform with this presentation. In August 2019, the Company sold certain assets and liabilities related to our Spence and Nicholson product lines for $84.5 million, subject to adjustment for working capital and other specified items of approximately $(0.5) million. The Spence and Nicholson product lines include steam regulators, control valves, safety relief valves, temperature regulators, steam traps and other steam accessories and solutions. The disposal group did not meet the criteria to be classified as discontinued operations. In September 2019, the Company obtained approval from its Board of Directors to dispose of the Distributed Valves ("DV") business in a transaction or transfer to a third-party purchaser or purchasers. The DV business is a long-cycle upstream oil and gas engineered valve business. The disposal group met the criteria to be classified as held for sale and a discontinued operation, and is recorded as such within our consolidated financial statements. All prior period comparative financial information has been reclassified to conform with this presentation. As of December 31, 2019, the Company has not yet secured a buyer for the DV business but is actively marketing the business for sale. The Company anticipates completing the disposition within twelve months. In December 2019, the Company entered into a definitive agreement to dispose of a non-core business, Instrumentation and Sampling (“I&S”) business. The I&S business manufactures fittings, regulators sampling systems and valves. The disposal group did not meet the criteria to be classified as a discontinued operation. However, it did meet the criteria for presentation as held for sale. Accordingly the I&S assets and liabilities were collapsed as held for sale within the consolidated balance sheet at December 31, 2019. In January 2020, the Company completed the sale of the I&S business to Crane Co. for $172 million in cash, subject to a working capital adjustment. See Note 23, Subsequent Events. For more information on the discontinued operations and held for sale transactions, see Note 3, Discontinued Operations and Assets Held for Sale.
