Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION Unless otherwise indicated, “we,” “us” and “our” mean SPX Corporation and its consolidated subsidiaries (“SPX”). We prepared the condensed consolidated financial statements pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim reporting. As permitted under those rules and regulations, certain footnotes or other financial information normally required by accounting principles generally accepted in the United States (“GAAP”) can be condensed or omitted. The financial statements represent our accounts after the elimination of intercompany transactions and, in our opinion, include the adjustments (consisting only of normal and recurring items) necessary for their fair presentation. We account for investments in unconsolidated companies where we exercise significant influence but do not have control using the equity method. In determining whether we are the primary beneficiary of a variable interest entity (“VIE”), we perform a qualitative analysis that considers the design of the VIE, the nature of our involvement and the variable interests held by other parties to determine which party has the power to direct the activities of the VIE that most significantly impact the entity’s economic performance, and which party has the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. We have an interest in a VIE, in which we are not the primary beneficiary, as a result of the sale of Balcke Dürr. See below and in Notes 3 and 16 for further discussion of the sale of Balcke Dürr. All other VIEs are considered immaterial, individually and in aggregate, to our condensed consolidated financial statements. Acquisition of Schonstedt On March 1, 2018, we completed the acquisition of Schonstedt Instrument Company (“Schonstedt”), a manufacturer and distributor of magnetic locator products used for locating underground utilities and other buried objects, for a purchase price of $16.3, net of cash acquired of $0.3. Schonstedt had revenues of approximately $9.0 for the twelve months prior to the acquisition. The assets acquired and liabilities assumed have been recorded at preliminary estimates of fair value as determined by management, based on information currently available and on current assumptions as to future operations, and are subject to change upon completion of acquisition accounting. The post-acquisition operating results of Schonstedt are reflected within our Detection and Measurement reportable segment. Sale of Balcke Dürr On December 30, 2016, we completed the sale of Balcke Dürr to a subsidiary of mutares AG (the “Buyer”). During the first quarter of 2017, we reduced the net loss associated with the sale of Balcke Dürr by $7.2, with such amount recorded to “Gain on disposition of discontinued operations, net of tax.” The reduction was comprised of an additional income tax benefit recorded for the sale of $8.4, partially offset by adjustments to liabilities retained in connection with the sale, net of tax, of $1.2. On April 30, 2018, we reached an agreement with the Buyer on the amount of cash and working capital at the closing date, as well as on various other claims, for a net payment to be made by the Buyer of Euro 3.0. The settlement is expected to result in a gain, which we will record in our condensed consolidated statement of operations for the three months ended June 30, 2018. Other Preparing financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. Actual results could differ from these estimates. The unaudited information included in this Quarterly Report on Form 10-Q should be read in conjunction with the consolidated financial statements contained in our Annual Report on Form 10-K for the year ended December 31, 2017. Interim results are not necessarily indicative of full year results. We have reclassified certain prior year amounts to conform to the current year presentation. Unless otherwise indicated, amounts provided in these Notes pertain to continuing operations only. See Note 3 for information on discontinued operations. We establish actual interim closing dates using a fiscal calendar, which requires our businesses to close their books on the Saturday closest to the end of the first calendar quarter, with the second and third quarters being 91 days in length. Our fourth quarter ends on December 31. The interim closing dates for the first, second and third quarters of 2018 are March 31, June 30 and September 29, compared to the respective April 1, July 1 and September 30, 2017 dates. We had one less day in the first quarter of 2018 and will have one more day in the fourth quarter of 2018 than in the respective 2017 periods. We do not believe the one less day during the first quarter of 2018 had a material impact on our consolidated operating results, when compared to the consolidated operating results for the respective 2017 period.

Preparing financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses.

We establish actual interim closing dates using a fiscal calendar, which requires our businesses to close their books on the Saturday closest to the end of the first calendar quarter, with the second and third quarters being 91 days in length. Our fourth quarter ends on December 31. The interim closing dates for the first, second and third quarters of 2018 are March 31, June 30 and September 29, compared to the respective April 1, July 1 and September 30, 2017 dates.
