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 Note 15 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. Sale of Dry Cooling Business On March 30, 2016, we completed the sale of our dry cooling business, a business previously within our Engineered Solutions reportable segment, to Paharpur Cooling Towers Limited (“Paharpur”) for cash proceeds of $45.9 (net of cash transferred with the business of $3.0), resulting in a gain during the quarter ended April 2, 2016 of $17.9. The gain includes a reclassification from “Equity” of other comprehensive income totaling $40.4 related to foreign currency translation. During the second quarter of 2016, we reduced the gain by $1.2 in connection with adjustments to certain liabilities retained from the sale. During the third quarter of 2016, we increased the gain by $1.7 in connection with the settlement of the final working capital associated with the business. In connection with the sale, we provided customary indemnifications to Paharpur. Accordingly, it is possible that the sales price and resulting gain for this divestiture may be materially adjusted in subsequent periods. Sale of Balcke Dürr Business On December 30, 2016, we completed the sale of Balcke Dürr to a subsidiary of mutares AG (the “Buyer”) for cash proceeds of less than $0.1. In addition, we left $21.1 of cash in Balcke Dürr at the time of the sale and provided the Buyer with a non-interest bearing loan of $9.1, payable in installments due at the end of 2018 and 2019. The results of Balcke Dürr are presented as a discontinued operation within the accompanying condensed consolidated financial statements. In connection with the sale, we recorded a net loss of $78.6 in the fourth quarter of 2016 to “Gain (loss) on disposition of discontinued operations, net of tax.” During the first quarter of 2017, we reduced the net loss associated with the sale of Balcke Dürr by $7.2. 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 of $1.2. During the second quarter of 2017, we increased the net loss associated with the sale of Balcke Dürr by $0.4, with the increase resulting from adjustments to liabilities retained in connection with the sale. The purchase agreement provided that existing parent company guarantees of approximately €79.0 and bank and surety bonds of approximately €79.0 would remain in place through each instrument’s expiration date, with such expiration dates ranging from 2017 to 2022. Balcke Dürr and the Buyer have provided us a full indemnity in the event that any of these guarantees or bonds are called. Also, Balcke Dürr has provided cash collateral of €4.0 and mutares AG has provided a guarantee of €5.0 as a security for the above indemnifications. In connection with the sale, we recorded a liability for the estimated fair value of the guarantees and bonds and an asset for the estimated fair value of the cash collateral and indemnities provided. See Note 15 for further details regarding these estimated fair values. The final sales price for Balcke Dürr is subject to adjustment based on cash and working capital existing at the closing date and is subject to agreement with the Buyer. Final agreement of the cash and working capital amounts with the Buyer has yet to occur. Accordingly, it is possible that the sales price and resulting loss for this divestiture may be materially adjusted in subsequent periods. 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, 2016. Interim results are not necessarily indicative of full year results. We have reclassified certain prior year amounts, including the results of discontinued operations, 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 2017 are April 1, July 1 and September 30, compared to the respective April 2, July 2 and October 1, 2016 dates. We had two fewer days in the first quarter of 2017 and will have one more day in the fourth quarter of 2017 than in the respective 2016 periods. We do not believe the two fewer days during the first quarter of 2017 had a material impact on our consolidated operating results for the first half of 2017, when compared to the consolidated operating results for the first half of 2016.
