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. Spin-Off of FLOW Business On September 26, 2015 (the “Distribution Date”), we completed the spin-off to our stockholders (the “Spin-Off”) of all the outstanding shares of SPX FLOW, Inc. (“SPX FLOW”), a wholly-owned subsidiary of SPX prior to the Spin-Off, which at the time of the Spin-Off held the businesses comprising our Flow Technology reportable segment, our Hydraulic Technologies business, and certain of our corporate subsidiaries (collectively, the “FLOW Business”). On the Distribution Date, each of our stockholders of record as of the close of business on September 16, 2015 (the “Record Date”) received one share of common stock of SPX FLOW for every share of SPX common stock held as of the Record Date. SPX FLOW is now an independent public company trading under the symbol “FLOW” on the New York Stock Exchange. Following the Spin-Off, SPX’s common stock continues to be listed on the New York Stock Exchange, but trades under the new ticker symbol, “SPXC”. The financial results of SPX FLOW for the three months ended March 28, 2015 have been classified as discontinued operations within the accompanying condensed consolidated financial statements. See Note 3 for additional information regarding discontinued operations. In connection with the Spin-Off, SPX and SPX FLOW entered into several administrative agreements covering various services, such as information technology, human resources and finance, to be provided by each party for a period of up to 12 months following the Distribution Date. These agreements contain customary mutual indemnification provisions. The financial activity associated with these agreements was not material to our condensed consolidated financial results for the quarter ended April 2, 2016. Sale of Dry Cooling Business On March 30, 2016, we completed the sale of our dry cooling business 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. The final sales price for the dry cooling business is subject to adjustment based on working capital existing at the closing date and is subject to agreement with the buyer. Final agreement of the working capital amount with the buyer has yet to occur. Additionally, we provided customary indemnifications to Paharpur in connection with the sale. Accordingly, it is possible that the sales price and resulting gain for this divestiture may be materially adjusted in subsequent periods. The assets and liabilities of the dry cooling business, as of December 31, 2015, have been classified as “held for sale” within the accompanying condensed consolidated balance sheet. See Note 3 for information on such assets and liabilities. New Segment Reporting Structure Prior to the Spin-Off, we aggregated certain of our operating segments into two reportable segments, Flow Technology and Thermal Equipment and Services, while our remaining operating segments, which included our Hydraulic Technologies business, were combined within an “All Other” category that we referred to as Industrial Products and Services and Other. As noted above, the Spin-Off included our Flow Technology reportable segment and our Hydraulic Technologies business. In addition, the Spin-Off resulted in a change of our chief operating decision maker (“CODM”). As a result of the Spin-Off, we realigned our segment reporting structure, effective for the quarter ended September 26, 2015. Under the realigned structure, our three reportable segments are as follows: HVAC, Detection and Measurement, and Power. The realigned segment reporting structure reflects the manner in which our new CODM is managing our business. See Note 4 for additional information regarding our realigned segment reporting structure. 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 2015 Annual Report on Form 10-K. Interim results are not necessarily indicative of full year results. We have reclassified certain prior year amounts, including (i) the results of discontinued operations, (ii) information on reportable segments, and (iii) debt issuance costs associated with the term loan under our senior credit facilities (see Note 2), 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 2016 are April 2, July 2 and October 1, compared to the respective March 28, June 27 and September 26, 2015 dates. We had six more days in the first quarter of 2016 and will have five fewer days in the fourth quarter of 2016 than in the respective 2015 periods. We do not believe the six additional days during the first quarter of 2016 had a material impact on our consolidated operating results, when compared to the consolidated operating results for the first quarter of 2015.
