(1) BASIS OF PRESENTATION

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 interests in VIEs, primarily joint ventures, in which we are the primary beneficiary and others in which we are not. Our VIEs are considered immaterial, individually and in aggregate, to our consolidated financial statements.

Our significant investments reported under the equity method are our 44.5% interest in the EGS Electrical Group, LLC and Subsidiaries (“EGS”) joint venture and our 45% interest in Shanghai Electric — SPX Engineering & Technologies Co., Ltd. (“Shanghai Electric JV”). We account for our EGS investment on a three-month lag, and its revenues and our equity earnings, as included in our condensed consolidated statements of operations, totaled $125.1 and $9.2 and $133.1 and $9.3 for the three months ended March 30, 2013 and March 31, 2012, respectively. The Shanghai Electric JV’s revenues and our equity earnings, as included in our condensed consolidated statements of operations, were not material for the three months ended March 30, 2013 and March 31, 2012. See Note 3 for further details on the Shanghai Electric JV.

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 2012 Annual Report on Form 10-K. 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. 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 2013 are March 30, June 29 and September 28, compared to the respective March 31, June 30 and September 29, 2012 dates. We had two fewer days in the first quarter of 2013 and will have one more day in the fourth quarter of 2013 than in the respective 2012 periods.
