BASIS OF PRESENTATION

BASIS OF PRESENTATION

(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 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 $127.5 and $8.6 and $121.8 and $6.7 for the three months ended September 29, 2012 and October 1, 2011, respectively. For the nine months ended September 29, 2012 and October 1, 2011, EGS’s revenues and our equity earnings, as included in our condensed consolidated statements of operations, totaled $387.2 and $25.1 and $355.1 and $20.0, 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 and nine months ended September 29, 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 2011 Annual Report on Form 10-K, as amended (“2011 Annual Report on Form 10-K/A”). Interim results are not necessarily indicative of full year results. We have reclassified certain prior year amounts, including the results of discontinued operations and reportable and other operating segment information, 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 and Note 4 for information on our reportable and other operating segments.

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 2012 are March 31, June 30 and September 29, compared to the respective April 2, July 2 and October 1, 2011 dates. We had one fewer day in the first quarter of 2012 and will have two more days in the fourth quarter of 2012 than in the respective 2011 periods.

NEW ACCOUNTING PRONOUNCEMENTS

Sep. 29, 2012

NEW ACCOUNTING PRONOUNCEMENTS

NEW ACCOUNTING PRONOUNCEMENTS

(2) NEW ACCOUNTING PRONOUNCEMENTS

The following is a summary of new accounting pronouncements that apply or may apply to our business.

In May 2011, the Financial Accounting Standards Board (“FASB”) issued guidance to develop a single, converged fair value framework, amend the requirements of fair value measurement and enhance related disclosure requirements, particularly for recurring Level 3 fair value measurements. This guidance clarifies the concepts of (i) the highest and best use and valuation premise for nonfinancial assets, (ii) application to financial assets and financial liabilities with offsetting positions in market risks or counterparty credit risk, (iii) premiums or discounts in fair value measurements and (iv) fair value measurement of an instrument classified in a reporting entity’s shareholders’ equity. The guidance is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2011, and must be applied prospectively. We adopted the guidance on January 1, 2012 with no material impact on our consolidated financial statements.

In June 2011, the FASB issued, and in December 2011 amended, guidance to revise the presentation of comprehensive income by requiring entities to report components of comprehensive income in either a single continuous statement of comprehensive income or two separate but consecutive statements. In annual periods, the single continuous statement of comprehensive income must include the components of net income, a total for net income, the components of other comprehensive income (“OCI”), a total for OCI, and a total for comprehensive income. The separate but consecutive statements must report components of net income and total net income in the statement of net income, which must be immediately followed by a statement of OCI that must include the components of OCI, a total for OCI, and a total for comprehensive income. In condensed financial statements of interim periods, an entity shall report a total for comprehensive income in a single continuous statement or in two consecutive statements. The guidance is effective for the first reporting period in fiscal years beginning after December 15, 2011 and must be applied retrospectively for all periods presented in the financial statements. We adopted the guidance on January 1, 2012 with no material impact on our consolidated financial statements.

In September 2011, the FASB issued an amendment to guidance related to testing goodwill for impairment. Under the revised guidance, entities testing goodwill for impairment have the option of performing a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test under the Intangibles — Goodwill and Other Topic of the Accounting Standards Codification (“Codification” or “ASC”). If an entity determines, on the basis of qualitative factors, that the fair value of the reporting unit is more likely than not less than the carrying amount, the two-step impairment test would be required. The amendment is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. We adopted this guidance on January 1, 2012 with no material impact on our consolidated financial statements.

In December 2011, the FASB issued an amendment to disclosure requirements related to offsetting, whereby entities are required to disclose both gross information and net information about both instruments and transactions eligible for offset in the statement of financial position and instruments and transactions subject to an agreement similar to a master netting arrangement. These disclosures assist users of financial statements in evaluating the effect or potential effect of netting arrangements on a company’s financial position, including the effect or potential effect of rights of setoff associated with the recognized assets and recognized liabilities within the scope. The amendment applies to a) recognized financial and derivative instruments that are offset in accordance with either ASC 210-20 or ASC 815-10 and b) financial and derivative instruments and other transactions that are subject to an enforceable master netting arrangement or similar agreement that covers similar instruments and transactions. This amendment will be effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods, and shall be applied retrospectively for all comparative periods presented. We have not yet adopted this guidance and do not expect the adoption to have a material impact on our consolidated financial statements.

In July 2012, the FASB issued an amendment to guidance related to testing indefinite-lived intangible assets, other than goodwill, for impairment. Under the revised guidance, entities testing such assets for impairment have the option of first performing a qualitative assessment to determine whether it is more likely than not that the carrying amount of an indefinite-lived intangible asset exceeds its fair value. If an entity determines, on the basis of qualitative factors, that it is more likely than not that the indefinite-lived intangible asset is impaired, then the entity shall calculate the fair value of the intangible asset and perform the quantitative impairment test in accordance with the Intangibles — Goodwill and Other Topic of the Codification. The amendment is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. Early adoption is permitted. We have not yet adopted this guidance and do not expect the adoption to have a material impact on our consolidated financial statements.

It includes the conveyance of information necessary for a user of the Company's financial information to understand all aspects and required disclosure information concerning all changes and error corrections reported in the Company's financial statements for the period.

Acquisitions

On March 21, 2012, in our Flow Technology reportable segment, we completed the acquisition of Seital S.r.l. (“Seital”), a supplier of disk centrifuges (separators and clarifiers) to the global food and beverage, biotechnology, pharmaceutical and chemical industries, for a purchase price of $28.8, net of cash acquired of $2.5 and including debt assumed of $0.8. Seital had revenues of approximately $14.0 in the twelve months prior to the date of acquisition.

On December 22, 2011, in our Flow Technology reportable segment, we completed the acquisition of Clyde Union (Holdings) S.A.R.L. (“Clyde Union”), a global supplier of pump technologies utilized in oil and gas processing, power generation and other industrial applications for an initial payment of 500.0 British Pounds (“GBP”), less debt assumed and other adjustments of GBP 11.0. In addition, the purchase price includes a potential earn-out payment (equal to Annual 2012 Group EBITDA (as defined by the related agreement) × 10, less GBP 475.0). In no event shall the earn-out payment be less than zero or more than GBP 250.0. The sellers of Clyde Union also contributed GBP 25.0 of cash to the acquired business at the time of sale.

We financed the acquisition with available cash and committed senior secured financing. See Note 10 to the condensed consolidated financial statements for further details on the senior secured financing. The estimated fair value of the contingent consideration (earn-out payment) was less than $1.0 at September 29, 2012 as well as at December 31, 2011.

The assets acquired and liabilities assumed were recorded at preliminary estimates of fair values as determined by management, based on information currently available and on current assumptions as to future operations, and are subject to change upon the completion of acquisition accounting, including the finalization of asset valuations. We are continuing to revise and finalize our estimates of fair value for certain assets and liabilities, which resulted in a net increase to goodwill of $57.9 during the nine months ended September 29, 2012. We will finalize our estimates of fair value during the fourth quarter of 2012.

The following is a summary of the recorded preliminary fair values of the assets acquired and liabilities assumed for Clyde Union at the date of acquisition, and reflects acquisition accounting adjustments recorded during the first three quarters of 2012:

Assets acquired:
Current assets, including cash and equivalents of $44.3	$	352.3
Property, plant and equipment	76.7
Goodwill	372.7
Intangible assets	378.8
Other assets	25.1
Total assets acquired	1,205.6
Liabilities assumed:
Current liabilities	270.4
Other long-term liabilities	166.4
Total liabilities assumed	436.8
Noncontrolling interests	1.8
Net assets acquired	$	767.0

The identifiable intangible assets acquired consist of trademarks, customer lists, customer relationships and technology of $76.8, $7.5, $234.4 and $60.1, respectively, with such amounts based on a preliminary assessment of the related fair values. The customer lists, customer relationships and technology assets are being amortized over 1.5, 30.0 and 27.0 years, respectively.

The qualitative factors that comprise the recorded goodwill include expected synergies from combining our existing and Clyde Union’s operations and expected market growth for existing Clyde Union operations, as well as other factors. None of this goodwill is deductible for income tax purposes.

The following unaudited pro forma information presents our after-tax results of operations for the three and nine months ended October 1, 2011, as if the acquisition of Clyde Union had taken place on January 1, 2011. The unaudited pro forma financial information is not intended to represent or be indicative of our consolidated results of operations that would have been reported had the acquisition been completed as of the date presented, and should not be taken as representative of our future consolidated results of operations. The pro forma results include estimates and assumptions that management believes are reasonable; however, these results do not include any anticipated cost savings or expenses of the planned integration of Clyde Union. These pro forma results of operations have been prepared for comparative purposes only and include the following adjustments to the October 1, 2011 historical results for the periods presented:

· Additional depreciation and amortization expense associated with the fair value adjustments to the acquired Clyde Union property, plant and equipment and intangible assets of $1.1 and $3.1 for the three and nine months ended October 1, 2011, respectively.

· The elimination of interest expense related to the portion of Clyde Union’s long-term debt that was paid off at the time of the acquisition of $3.2 and $10.0 for the three and nine months ended October 1, 2011, respectively.

· The addition of interest expense associated with the term loans that were drawn down in order to finance the Clyde Union acquisition of $5.3 and $15.2 for the three and nine months ended October 1, 2011, respectively.

· The elimination of rent expense associated with a facility in Scotland that had been leased by Clyde Union and that we purchased on December 23, 2011 of $0.6 and $1.6 for the three and nine months ended October 1, 2011, respectively.

· A reduction in bonding costs for Clyde Union due to more favorable rates under our senior credit facilities of $1.7 and $4.2 for the three and nine months ended October 1, 2011, respectively.

· The above modifications were adjusted for the applicable income tax impact.

On October 31, 2011, in our Flow Technology reportable segment, we completed the acquisition of e&e Verfahrenstechnik GmbH (“e&e”), a supplier of extraction, evaporation, vacuum and freeze drying technologies to the global food and beverage, pharmaceutical and bioenergy industries for a purchase price of approximately 11.7 Euros, net of cash assumed of 3.8 Euros, with an additional potential earn-out of 3.5 Euros. e&e had revenues of approximately 15.3 Euros in the twelve months prior to the date of acquisition.

In March 2011, in our Flow Technology reportable segment, we completed the acquisition of B.W. Murdoch Ltd. (“Murdoch”), an engineering company supplying processing solutions for the food and beverage industry, for a purchase price of $8.1, after payment of a working capital settlement of $0.7 during the third quarter of 2011. Murdoch had revenues of approximately $13.0 in the twelve months prior to the date of acquisition.

The pro forma effects of the Seital, e&e and Murdoch acquisitions were not material, individually or in the aggregate, to our results of operations.

Discontinued Operations

As part of our operating strategy, we regularly review and negotiate potential divestitures, some of which are or may be material. As a result of this continual review, we determined that certain of our businesses would be better strategic fits with other companies or investors.

We report businesses or asset groups as discontinued operations when, among other things, we commit to a plan to divest the business or asset group, actively begin marketing the business or asset group, and when the sale of the business or asset group is deemed probable within the next twelve months.

On January 23, 2012, we entered into an agreement to sell our Service Solutions business to Robert Bosch GmbH for cash proceeds of $1,150.0. We expect the sale to close during December 2012, resulting in a net gain of approximately $450.0. We have reported, for all periods presented, the financial condition, results of operations, and cash flows of this business as a discontinued operation in our condensed consolidated financial statements.

In addition to the business discussed above, we recognized net losses of $0.7 and $1.6 during the three and nine months ended September 29, 2012, respectively, and net gains of $0.4 and $1.2 during the three and nine months ended October 1, 2011, respectively, resulting from adjustments to gains/losses on sales from previously discontinued businesses. Refer to the consolidated financial statements contained in our 2011 Annual Report on Form 10-K/A for the disclosure of all discontinued businesses during the 2009 through 2011 period.

The final sales price for certain of the divested businesses is subject to adjustment based on working capital existing at the respective closing dates. The working capital figures are subject to agreement with the buyers or, if we cannot come to agreement, an arbitration or other dispute-resolution process. Final agreement of the working capital figures for certain of these transactions has yet to occur. In addition, changes in estimates associated with liabilities retained in connection with a business divestiture (e.g., income taxes) may occur. It is possible that the sales price and resulting gains/losses on these, and other previous divestitures, may be materially adjusted in subsequent periods.

For the three and nine months ended September 29, 2012 and October 1, 2011, income from discontinued operations and the related income taxes are shown below:

	Three months ended						Nine months ended

Formation of Shanghai Electric JV

On December 30, 2011, we and Shanghai Electric Group Co., Ltd. established the Shanghai Electric JV, a joint venture to supply dry cooling and moisture separator reheater products and services to the power sector in China and other selected regions of the world. We contributed and sold certain assets of our dry cooling products business in China to the joint venture in consideration for a 45% ownership interest in the joint venture and cash payments of RMB 96.7, with RMB 51.5 received on January 18, 2012, RMB 25.8 to be received no later than December 31, 2012, and the remaining RMB payment contingent upon the joint venture achieving defined sales order volumes. In addition, we are licensing our dry cooling and moisture separator reheater technologies to the joint venture, for which we will receive a royalty. We also will continue to manufacture dry cooling components in our China factories and have entered into an exclusive supply agreement with the joint venture for these products. Final approval for the transaction was received January 13, 2012. We accounted for the transaction under the deconsolidation criteria of the Codification and thus recorded a pre-tax gain during the first quarter of 2012 of $20.5 within “Other income (expense), net.” The amount of the pre-tax gain is equal to the difference between (i) the fair value of the consideration received and to be received plus the fair value of our retained non-controlling investment in the dry cooling products business in China and (ii) the carrying value of the assets contributed and sold to the joint venture. We account for our investment in the Shanghai Electric JV under the equity method of accounting, as we exercise significant influence but do not have control over the joint venture. The carrying amount of our investment in the Shanghai Electric JV was $33.2 at September 29, 2012 and is reported in “Other assets” within our condensed consolidated balance sheet.

INFORMATION ON REPORTABLE SEGMENTS AND OTHER OPERATING SEGMENTS

(4) INFORMATION ON REPORTABLE SEGMENTS AND OTHER OPERATING SEGMENTS

We are a global, multi-industry manufacturer of highly specialized, engineered solutions with operations in over 35 countries. We offer a diverse collection of products, such as pumps, valves, fluid handling equipment, metering and mixing solutions, cooling, heating and ventilation products, power transformers, and TV and radio broadcast antennas. Our products are used by a broad array of customers in various industries, including food and beverage processing, power generation, chemical processing, pharmaceuticals, infrastructure, mineral processing, petrochemical, telecommunications and transportation.

Prior to 2012, we aggregated our operating segments into four reportable segments; however, because of the impending sale of our Service Solutions business (a business previously reported within the Test & Measurement reportable segment) and its current classification as a discontinued operation, we are no longer reporting the remaining two businesses of the Test & Measurement reportable segment as a separate reportable segment, as the operating results of these two businesses have not been, and are not expected to be, material to our consolidated operating results. These two businesses, along with our remaining operating segments, which do not meet the quantitative threshold criteria of the Segment Reporting Topic of the Codification, have been combined within our “All Other” category, which we refer to as Industrial Products and Services. This is not considered a reportable segment.

The factors considered in determining our aggregated segments are the economic similarity of the businesses, the nature of products sold or services provided, production processes, types of customers and distribution methods. In determining our segments, we apply the threshold criteria of the Segment Reporting Topic of the Codification to operating income or loss of each segment before considering impairment and special charges, pensions and postretirement expense, stock-based compensation and other indirect corporate expenses. This is consistent with the way our chief operating decision maker evaluates the results of each segment.

Flow Technology Reportable Segment

Our Flow Technology segment designs, manufactures and markets products and solutions to process, blend, filter, dry, meter and transport fluids with a focus on creating innovative new products and systems, and also provides comprehensive aftermarket support services. Primary offerings include engineered pumps, mixers, process systems, heat exchangers, valves, and dehydration and drying technologies. The segment continues to focus on optimizing its global footprint while taking advantage of cross-product integration opportunities and increasing its competitive position in global end markets. Flow Technology’s solutions focus on key business drivers, such as product flexibility, process optimization, sustainability and safety.

Thermal Equipment and Services Reportable Segment

Our Thermal Equipment and Services segment engineers, manufactures and services cooling, heating and ventilation products for markets throughout the world. Primary offerings include dry, wet and hybrid cooling systems for the power generation, refrigeration, HVAC and industrial markets, as well as boiler, heating and ventilation products for the commercial and residential markets. This segment also provides thermal components for power generation plants and engineered services to maintain, refurbish, upgrade and modernize power stations. The segment continues to focus on expanding its global reach, as well as its thermal components and service offerings. The segment’s South African subsidiary has a Black Economic Empowerment shareholder, which holds a noncontrolling 25.1% interest.

Industrial Products and Services

Industrial Products and Services comprises operating segments that design, manufacture and market power systems, industrial tools and hydraulic units, precision machine components for the aerospace industry, crystal growing machines for the solar power generation market, television, radio and cell phone and data transmission broadcast antenna systems, communications and signal monitoring systems, fare collection systems, portable cable and pipe locators, and precision controlled industrial ovens and chambers. These operating segments continue to focus on global expansion opportunities.

Corporate Expense

Corporate expense generally relates to the cost of our Charlotte, NC corporate headquarters and our Asia Pacific center in Shanghai, China.

Estimated annual amortization expense related to these intangible assets is $9.2 for the remainder of 2012, $35.0 in 2013, $30.6 in 2014, $30.1 in 2015, and $29.9 in 2016.

At September 29, 2012, the net carrying value of intangible assets with determinable lives consisted of $461.3 in the Flow Technology reportable segment, $53.6 in the Thermal Equipment and Services reportable segment, and $10.4 in Industrial Products and Services. Trademarks with indefinite lives consisted of $287.5 in the Flow Technology reportable segment, $130.2 in the Thermal Equipment and Services reportable segment, and $24.1 in Industrial Products and Services.

We perform our annual goodwill impairment testing during the fourth quarter in conjunction with our annual financial planning process. In addition, we test goodwill for impairment on a more frequent basis if an event occurs, or circumstances change, that would more likely than not reduce the fair value of a reporting unit below its carrying value. A significant amount of judgment is involved in determining if an indication of impairment has occurred between annual testing dates. Such indications may include: a significant decline in expected future cash flows; a significant adverse change in legal factors or the business climate; unanticipated competition; and a more likely than not expectation of selling or disposing all, or a portion, of a reporting unit.

Based on our annual impairment testing during the fourth quarter of 2010, our SPX Heat Transfer Inc. reporting unit had an estimated fair value that was comparable to the carrying value of its net assets. In the second quarter of 2011, SPX Heat Transfer Inc. experienced an additional decline in its revenues and profitability, furthering a trend which began late in the first quarter of 2011, in comparison to (i) recent historical results and (ii) expected results for the period, due to the challenging conditions within the U.S. power market. As such, during the second quarter of 2011, we updated the projection of future discounted cash flows for SPX Heat Transfer Inc., which indicated the reporting unit’s fair value was less than the carrying value of its net assets. Accordingly, we recorded an impairment charge of $24.7 during the second quarter of 2011 associated with SPX Heat Transfer Inc.’s goodwill ($17.2) and indefinite-lived intangible assets ($7.5).

- Definition

The entire disclosure for the aggregate amount of goodwill and a description of intangible assets, which may include (a) for amortizable intangible assets (also referred to as finite-lived intangible assets), the carrying amount, the amount of any significant residual value, and the weighted-average amortization period, (b) for intangible assets not subject to amortization (also referred to as indefinite-lived intangible assets), the carrying amount, and (c) the amount of research and development assets acquired and written off in the period, including the line item in the income statement in which the amounts written off are aggregated, if not readily apparent from the income statement. Also discloses (a) for amortizable intangibles assets in total and by major class, the gross carrying amount and accumulated amortization, the total amortization expense for the period, and the estimated aggregate amortization expense for each of the five succeeding fiscal years, (b) for intangible assets not subject to amortization the carrying amount in total and by major class, and (c) for goodwill, in total and for each reportable segment, the changes in the carrying amount of goodwill during the period (including the aggregate amount of goodwill acquired, the aggregate amount of impairment losses recognized, and the amount of goodwill included in the gain (loss) on disposal of a reporting unit). If any part of goodwill has not been allocated to a reportable segment, discloses the unallocated amount and the reasons for not allocating. For each impairment loss recognized related to an intangible asset (excluding goodwill), discloses: (a) a description of the impaired intangible asset and the facts and circumstances leading to the impairment, (b) the amount of the impairment loss and the method for determining fair value, (c) the caption in the income statement or the statement of activities in which the impairment loss is aggregated, and (d) the segment in which the impaired intangible asset is reported. For each goodwill impairment loss recognized, discloses: (a) a description of the facts and circumstances leading to the impairment, (b) the amount of the impairment loss and the method of determining the fair value of the associated reporting unit, and (c) if a recognized impairment loss is an estimate not finalized and the reasons why the estimate is not final. May also disclose the nature and amount of any significant adjustments made to a previous estimate of an impairment loss.

Less: current maturities of long-term debt(1)	4.2									331.1
Total long-term debt	$	1,925.6								$	1,594.3

(1)	On February 8, 2012, the lenders under our senior credit facilities agreed, with respect to the proceeds from the pending sale of our Service Solutions business, to waive the mandatory prepayments required by the senior credit facilities. The waiver requires that a portion of the proceeds from the pending sale be used to repay $325.0 of the term loans under our senior credit facilities ($300.0 for Term Loan 1 and $25.0 for Term Loan 2). As we expect the sale to close in December 2012 and to make these debt repayments at the time of the closing, we have classified $325.0 of the term loans as ‘‘Current maturities of long-term debt’’ within our condensed consolidated balance sheet as of September 29, 2012. In addition, we have allocated approximately $2.0 and $7.0 of interest expense associated with the $325.0 of expected term loan repayments to discontinued operations within our condensed consolidated statements of operations for the three and nine months ended September 29, 2012, respectively.

(2)	Under this arrangement, we can borrow, on a continuous basis, up to $130.0, as available.

(3)	Includes balances under a purchase card program of $36.9 and $40.4 at September 29, 2012 and December 31, 2011, respectively.

(4)	“Other” includes debt assumed and foreign currency translation on any debt instruments denominated in currencies other than the U.S. dollar.

Senior Credit Facilities

We have senior credit facilities with a syndicate of lenders that provide for committed senior secured financing in the initial amount of $2,600.0, consisting of the following (each with a final maturity of June 30, 2016, except for the $325.0 relating to the term loans as described above):

· An incremental term loan (“Term Loan 1”), in an aggregate principal amount of $300.0;

· An incremental term loan (“Term Loan 2”), in an aggregate principal amount of $500.0;

· A domestic revolving credit facility, available for loans and letters of credit, in an aggregate principal amount up to $300.0;

· A global revolving credit facility, available for loans in U.S. Dollars, Euros, British Pounds and other currencies in an aggregate principal amount up to the equivalent of $300.0;

· A participation foreign credit instrument facility, available for performance letters of credit and guarantees, in an aggregate principal amount in various currencies up to the equivalent of $1,000.0; and

· A bilateral foreign credit instrument facility, available for performance letters of credit and guarantees, in an aggregate principal amount in various currencies up to the equivalent of $200.0.

The remaining balance on Term Loan 2 (i.e., the remaining balance after payment of the $25.0 noted above in connection with the sale of our Service Solutions business) is repayable in quarterly installments (with annual aggregate repayments, as a percentage of the initial principal amount, adjusted for prepayments, of 0% for 2012, 0% for 2013, 15% for 2014 and 20% for 2015, together with a single quarterly payment of 5% at the end of the first fiscal quarter of 2016), with the remaining balance repayable in full on June 30, 2016.

Our senior credit facilities require that we maintain:

· A Consolidated Interest Coverage Ratio (as defined in the credit agreement generally as the ratio of consolidated adjusted EBITDA for the four fiscal quarters ended on such date to consolidated interest expense for such period) as of the last day of any fiscal quarter of at least 3.50 to 1.00; and

· A Consolidated Leverage Ratio as of the last day of any fiscal quarter of not more than 3.25 to 1.00 (or 3.50 to 1.00 for the four fiscal quarters after certain permitted acquisitions by us).

Our senior credit facilities also contain covenants that, among other things, restrict our ability to incur additional indebtedness, grant liens, make investments, loans, guarantees or advances, make restricted junior payments, including dividends, redemptions of capital stock and voluntary prepayments or repurchase of certain other indebtedness, engage in mergers, acquisitions or sales of assets, enter into sale and leaseback transactions or engage in certain transactions with affiliates and otherwise restrict certain corporate activities. We do not expect these covenants to restrict our liquidity, financial condition or access to capital resources in the foreseeable future. Our senior credit facilities also contain customary representations, warranties, affirmative covenants, and events of default.

We are permitted under our senior credit facilities to repurchase our capital stock and pay cash dividends in an unlimited amount if our Consolidated Leverage Ratio is (after giving pro forma effect to such payments) less than 2.50 to 1.00. If our Consolidated Leverage Ratio is (after giving pro forma effect to such payments) greater than or equal to 2.50 to 1.00, the aggregate amount of such repurchases and dividend declarations cannot exceed (A) $100.0 in any fiscal year plus (B) an additional amount for all such repurchases and dividend declarations made after June 30, 2011 equal to the sum of (i) $300.0 and (ii) a positive amount equal to 50% of cumulative Consolidated Net Income (as defined in the credit agreement generally as consolidated net income subject to certain adjustments solely for the purposes of determining this basket) during the period from July 1, 2011 to the end of the most recent fiscal quarter preceding the date of such repurchase or dividend declaration for which financial statements have been (or were required to be) delivered (or, in case such Consolidated Net Income is a deficit, minus 100% of such deficit).

At September 29, 2012, we had $70.3 and $798.7 of outstanding letters of credit issued under our revolving credit and our foreign credit instrument facilities of our senior credit agreement, respectively. In addition, we had $5.7 of letters of credit outstanding under separate arrangements in China, India and South Africa.

The weighted-average interest rate of our outstanding borrowings under our senior credit facilities was approximately 2.39% at September 29, 2012.

At September 29, 2012, we were in compliance with all covenant provisions of our senior credit facilities, and the senior credit facilities did not impose any restrictions on our ability to repurchase shares or pay dividends, other than those inherent in the credit agreement. In addition, we were in compliance with all covenant provisions of our senior notes as of September 29, 2012.

- Definition

The entire disclosure for information about short-term and long-term debt arrangements, which includes amounts of borrowings under each line of credit, note payable, commercial paper issue, bonds indenture, debenture issue, own-share lending arrangements and any other contractual agreement to repay funds, and about the underlying arrangements, rationale for a classification as long-term, including repayment terms, interest rates, collateral provided, restrictions on use of assets and activities, whether or not in compliance with debt covenants, and other matters important to users of the financial statements, such as the effects of refinancing and noncompliance with debt covenants.

DERIVATIVE FINANCIAL INSTRUMENTS

9 Months Ended

Sep. 29, 2012

DERIVATIVE FINANCIAL INSTRUMENTS

DERIVATIVE FINANCIAL INSTRUMENTS

(11) DERIVATIVE FINANCIAL INSTRUMENTS

Currency Forward Contracts

We manufacture and sell our products in a number of countries and, as a result, are exposed to movements in foreign currency exchange rates. Our objective is to preserve the economic value of non-functional currency denominated cash flows and to minimize their impact. Our principal currency exposures relate to the Euro, Chinese Yuan, South African Rand and British Pound.

From time to time, we enter into currency protection agreements (“FX forward contracts”) to manage the exposure on contracts with forecasted transactions denominated in non-functional currencies and to manage the risk of transaction gains and losses associated with assets/liabilities denominated in currencies other than the functional currency of certain subsidiaries. In addition, some of our contracts contain currency forward embedded derivatives (“FX embedded derivatives”), as the currency of exchange is not “clearly and closely” related to the functional currency of either party to the transaction. Certain of our FX forward contracts are designated as cash flow hedges, as deemed appropriate. To the extent these derivatives are effective in offsetting the variability of the hedged cash flows, changes in the derivatives’ fair value are not included in current earnings, but are included in accumulated other comprehensive income (“AOCI”). These changes in fair value will subsequently be reclassified into earnings as a component of revenues or cost of products sold, as applicable, when the forecasted transaction impacts earnings. In addition, if the forecasted transaction is no longer probable, the cumulative change in the derivatives’ fair value will be recorded as a component of “Other income (expense), net” in the period it occurs. To the extent that a previously designated hedging transaction is no longer an effective hedge, any ineffectiveness measured in the hedging relationship is recorded in earnings in the period it occurs. We had FX forward contracts with an aggregate notional amount of $115.2 and $66.1 outstanding as of September 29, 2012 and December 31, 2011, respectively. These FX forward contracts typically have maturity dates ranging from one to two years. We had FX embedded derivatives with an aggregate notional amount outstanding of $111.4 and $73.2 at September 29, 2012 and December 31, 2011, respectively. The unrealized loss, net of taxes, recorded in AOCI related to FX forward contracts was $3.6 and $3.7 as of September 29, 2012 and December 31, 2011, respectively. We anticipate reclassifying approximately $2.8 of the unrealized loss to income over the next 12 months.

Commodity Contracts

From time to time, we enter into commodity contracts to manage the exposure on forecasted purchases of commodity raw materials (“commodity contracts”). At September 29, 2012 and December 31, 2011, the outstanding notional amount of commodity contracts was 4.1 million and 2.9 million pounds of copper, respectively. We designate and account for these contracts as cash flow hedges and, to the extent these commodity contracts are effective in offsetting the variability of the forecasted purchases, the change in fair value is included in AOCI. We reclassify the AOCI associated with our commodity contracts to cost of products sold when the forecasted transaction impacts earnings. The unrealized gain (loss), net of taxes, recorded in AOCI was $0.3 and $(0.7) as of September 29, 2012 and December 31, 2011, respectively. We anticipate reclassifying the unrealized gain to income over the next 12 months. The amount of gain/loss recognized during the periods ended September 29, 2012 and October 1, 2011 related to the ineffectiveness of the hedges was not material.

The following summarizes the fair value of our derivative financial instruments:

	September 29, 2012				December 31, 2011

During the three and nine months ended September 29, 2012, losses of $0.2 and $0.3 were recognized in other expense, net relating to derivative ineffectiveness and amounts excluded from effectiveness testing. During the nine months ended October 1, 2011, losses of $0.2 were recognized in other expense, net relating to derivative ineffectiveness and amounts excluded from effectiveness testing.

The following summarizes the effect of derivative financial instruments not designated as cash flow hedging relationships on the condensed consolidated statements of operations for the three months ended September 29, 2012 and October 1, 2011:

(12) EQUITY AND STOCK-BASED COMPENSATION

Earnings Per Share

The following table sets forth the number of weighted-average shares outstanding used in the computation of basic and diluted income per share:

	Three months ended		Nine months ended
	September 29,	October 1,	September 29,	October 1,
	2012	2011	2012	2011
Weighted-average shares outstanding used in basic income per share	49.958	50.618	50.174	50.480
Dilutive securities — employee stock options and restricted stock units	0.080	0.186	0.625	0.559
Weighted-average number of common and dilutive securities used for calculating diluted income per share	50.038	50.804	50.799	51.039

The total number of stock options that were not included in the computation of diluted income per share because their exercise price was greater than the average market price of common shares was 0.003 for both the three and nine months ended September 29, 2012, respectively, and 0.128 and 0.093 for the three and nine months ended October 1, 2011, respectively. For the three and nine months ended September 29, 2012, 1.784 and 0.931 unvested restricted stock units, respectively, were excluded from the computation of diluted income per share, compared to 1.316 and 0.443 for the three and nine months ended October 1, 2011.

Stock-based Compensation

Under the 2002 Stock Compensation Plan, as amended in 2006, 2011 and 2012, up to 3.423 shares of our common stock were available for grant at September 29, 2012. The 2002 Stock Compensation Plan permits the issuance of new shares or shares from treasury upon the exercise of options, vesting of restricted stock units or granting of restricted stock. Each share of restricted stock and restricted stock unit granted reduces availability by two shares.

During the nine months ended September 29, 2012 and October 1, 2011, we classified excess tax benefits from stock-based compensation of $3.4 and $6.5, respectively, as financing cash flows and included such amounts in “Proceeds from the exercise of employee stock options and other, net of minimum withholdings paid on behalf of employees for net share settlements” within our condensed consolidated statements of cash flows.

Restricted stock or restricted stock units may be granted to certain eligible employees or non-employee directors in accordance with applicable equity compensation plan documents and agreements. Subject to participants’ continued employment and other plan terms and conditions, the restrictions lapse and awards generally vest over three years. Market (“company performance”) thresholds have been instituted for vesting of the significant majority of restricted stock and restricted stock unit awards. This vesting is based on SPX shareholder return versus the S&P 500 composite index. On each vesting date, we compare the SPX shareholder return to the performance of the S&P 500 composite index for the prior year and for the cumulative period since the date of the grant. If SPX outperforms the S&P 500 composite index for the prior year, the one-third portion of the grant associated with that year will vest. If SPX outperforms the S&P composite index for the cumulative period, any unvested portion of the grant that was subject to vesting on or prior to the vesting date will vest. Additionally, a portion of our restricted stock and restricted stock unit awards vest based on the passage of time since the grant date. Restricted stock and restricted stock units that do not vest within the three-year vesting period are forfeited.

We grant restricted stock to non-employee directors under the 2006 Non-Employee Directors’ Stock Incentive Plan (the “Directors’ Plan”) and the 2002 Stock Compensation Plan. Under the Directors’ Plan, up to 0.013 shares of our common stock were available for grant at September 29, 2012. Restricted stock grants have a three-year vesting period based on SPX shareholder return versus the S&P 500 composite index and are subject to the same company performance thresholds for employee awards described in the preceding paragraph. Restricted stock that does not vest within the three-year vesting period in accordance with these performance requirements is forfeited.

Stock options may be granted to key employees in the form of incentive stock options or nonqualified stock options. The option price per share may be no less than the fair market value of our common stock at the close of business on the day prior to the date of grant. Upon exercise, the employee has the option to surrender previously owned shares at current value in payment of the exercise price and/or for withholding tax obligations, and, subject to certain restrictions, may receive a reload option having an exercise price equal to the current market value for the number of shares so surrendered. The reload option expires at the same time that the exercised option would have expired. Any future issuances of options under the plan will not have a reload feature, pursuant to the terms of the plan. We have not granted options to any of our employees since 2004. All outstanding options are vested as of September 29, 2012.

The recognition of compensation expense for share-based awards, including stock options, is based on their grant date fair values. The fair value of each award is amortized over the lesser of the award’s requisite or derived service period, which is generally up to three years. Compensation expense within income from continuing operations related to restricted stock and restricted stock units totaled $33.9 and $32.9 for the nine months ended September 29, 2012 and October 1, 2011, respectively, with the related tax benefit being $12.9 and $12.3 for the periods ended September 29, 2012 and October 1, 2011, respectively.

We use the Monte Carlo simulation model valuation technique to determine the fair value of our restricted stock and restricted stock units that contain a “market condition.” The Monte Carlo simulation model utilizes multiple input variables that determine the probability of satisfying the market condition stipulated in the award and calculates the fair value of each restricted stock and restricted stock unit award. We used the following assumptions in determining the fair value of the awards granted on January 2, 2012 and March 1, 2011:

							Correlation
							between total
							shareholder
	Annual expected						return for SPX
	stock price		Annual expected				and S&P 500
	volatility		dividend yield		Risk-free interest rate		Composite Index
January 2, 2012:
SPX Corporation	44.3	%	1.60	%	0.44	%	0.7365
S&P 500 Composite Index	23.1	%	n/a		0.44	%
March 1, 2011:
SPX Corporation	61.0	%	1.27	%	1.03	%	0.7559
S&P 500 Composite Index	30.3	%	n/a		1.03	%

Annual expected stock price volatility is based on the three-year historical volatility. The annual expected dividend yield is based on annual expected dividend payments and the stock price on the date of grant. The average risk-free interest rate is based on the one-year through three-year daily treasury yield curve rate as of the grant date.

The following table summarizes the restricted stock and restricted stock unit activity from December 31, 2011 through September 29, 2012:

			Weighted-Average
	Unvested Restricted Stock		Grant-Date Fair
	and Restricted Stock Units		Value Per Share
Outstanding at December 31, 2011	1.440		$	54.38
Granted	0.807		50.33
Vested	(0.204	)	35.03
Forfeited	(0.044	)	55.20
Outstanding at September 29, 2012	1.999		54.73

As of September 29, 2012, there was $22.3 of unrecognized compensation cost related to restricted stock and restricted stock unit compensation arrangements. We expect this cost to be recognized over a weighted-average period of 1.6 years.

The following table shows stock option activity from December 31, 2011 through September 29, 2012:

			Weighted-
			Average Exercise
	Shares		Price
Options outstanding and exercisable at December 31, 2011	0.364		$	54.87
Exercised	(0.151	)	39.73
Forfeited	(0.177	)	69.42
Options outstanding and exercisable at September 29, 2012	0.036		46.93

The weighted-average remaining term, in years, of stock options outstanding and exercisable at September 29, 2012 was 0.5. The total number of in-the-money options exercisable on September 29, 2012 was 0.033. Aggregate intrinsic value (market value of stock less the option exercise price) represents the total pre-tax intrinsic value, based on our closing stock price on September 29, 2012, which would have been received by the option holders had all in-the-money option holders exercised their options as of that date. The aggregate intrinsic value of the options outstanding and exercisable at September 29, 2012 was $0.8. The aggregate intrinsic value of options exercised during the first nine months of 2012 was $5.3, while the related amount for the first nine months of 2011 was $2.5.

Accumulated Other Comprehensive Loss

The components of the balance sheet caption “Accumulated other comprehensive loss” were as follows:

	September 29,			December 31,
	2012			2011
Foreign currency translation adjustment	$	200.3		$	199.7
Net unrealized losses on qualifying cash flow hedges, net of tax benefit of $2.3 and $2.9, respectively	(3.3		)	(4.4		)
Net unrealized losses on available-for-sale securities	(3.0		)	(1.5		)
Pension and postretirement liability adjustment and other, net of tax benefit of $266.7 and $274.3, respectively (1)	(427.1		)	(440.3		)
Accumulated other comprehensive loss	$	(233.1	)	$	(246.5	)

(1)	At both September 29, 2012 and December 31, 2011, includes $3.8 related to our share of the pension liability adjustment for EGS.

Common Stock in Treasury

On February 16, 2012, we entered into a written trading plan under Rule 10b5-1 of the Securities and Exchange Act of 1934, as amended, to facilitate the repurchase of up to $350.0 of shares of our common stock on or before February 14, 2013, in accordance with a share repurchase program authorized by our Board of Directors. During the first half of 2012, 0.992 shares of our common stock were repurchased for cash consideration of $75.0, with the remainder scheduled to be repurchased following the consummation of the sale of the Service Solutions business, in accordance with the share repurchase program. There were no common stock repurchases during the nine months ended October 1, 2011.

During the nine months ended September 29, 2012, “Common stock in treasury” was decreased by the settlement of restricted stock units issued from treasury stock of $3.9 and increased by $1.8 for common stock that was surrendered by recipients of restricted stock as a means of funding the related minimum income tax withholding requirements.

During the nine months ended October 1, 2011, “Common stock in treasury” was decreased by the settlement of restricted stock units issued from treasury stock of $12.7 and increased by $7.0 for common stock that was surrendered by recipients of restricted stock as a means of funding the related minimum income tax withholding requirements.

Dividends

The dividends declared during each of the first three quarters of 2012 and 2011 were $0.25 per share and totaled $12.8, $12.7 and $12.7 during the first, second and third quarters of 2012, respectively, and $12.7, $12.8 and $12.7 during the first, second and third quarters of 2011, respectively. Third quarter dividends were paid on October 3, 2012 and October 4, 2011.

CONTINGENCIES AND OTHER MATTERS

CONTINGENCIES AND OTHER MATTERS

(13) CONTINGENCIES AND OTHER MATTERS

General

Numerous claims, complaints and proceedings arising in the ordinary course of business, including those relating to litigation matters (e.g., class actions, derivative lawsuits and contracts, intellectual property and competitive claims), environmental matters, and risk management matters (e.g., product and general liability, automobile, and workers’ compensation claims), have been filed or are pending against us and certain of our subsidiaries. Additionally, we may become subject to significant claims of which we are currently unaware, or the claims of which we are aware may result in us incurring a significantly greater liability than we anticipate. This may also be true in connection with past or future acquisitions. While we maintain property, cargo, auto, product, general liability, environmental, and directors’ and officers’ liability insurance and have acquired rights under similar policies in connection with acquisitions that we believe cover a portion of these claims, this insurance may be insufficient or unavailable (e.g., because of insurer insolvency) to protect us against potential loss exposures. In addition, we have increased our self-insurance limits over the past several years. While we believe we are entitled to indemnification from third parties for some of these claims, these rights may be insufficient or unavailable to protect us against potential loss exposures. We believe, however, that our accruals related to these items are sufficient and that these items and our rights to available insurance and indemnity will be resolved without material effect, individually or in the aggregate, on our financial position, results of operations and cash flows. These accruals totaled $543.7 (including $497.1 for risk management matters) and $558.3 (including $495.6 for risk management matters) at September 29, 2012 and December 31, 2011, respectively. Of these amounts, $488.5 and $491.8 were included in “Other long-term liabilities” within our condensed consolidated balance sheets at September 29, 2012 and December 31, 2011, respectively, with the remainder included in “Accrued expenses.” It is reasonably possible that our ultimate liability for these items could exceed the amount of the recorded accruals; however, we believe the estimated amount of any potential additional liability would not have a material effect, individually or in the aggregate, on our financial position, results of operations or cash flows.

We had insurance recovery assets related to risk management matters of $428.5 and $428.9 at September 29, 2012 and December 31, 2011, respectively, included in “Other assets” within our condensed consolidated balance sheets.

Litigation Matters

We are subject to litigation matters that arise in the normal course of business. We believe these matters are either without merit or of a kind that should not have a material effect, individually or in the aggregate, on our financial position, results of operations or cash flows.

Environmental Matters

Our operations and properties are subject to federal, state, local and foreign regulatory requirements relating to environmental protection. It is our policy to comply fully with all applicable requirements. As part of our effort to comply, we have a comprehensive environmental compliance program that includes environmental audits conducted by internal and external independent professionals, as well as regular communications with our operating units regarding environmental compliance requirements and anticipated regulations. Based on current information, we believe that our operations are in substantial compliance with applicable environmental laws and regulations, and we are not aware of any violations that could have a material effect, individually or in aggregate, on our business, financial condition, results of operations or cash flows. We have liabilities for site investigation and/or remediation at 97 sites that we own or control. In addition, while we believe that we maintain adequate accruals to cover the costs of site investigation and/or remediation, we cannot provide assurance that new matters, developments, laws and regulations, or stricter interpretations of existing laws and regulations will not materially affect our business or operations in the future.

Our environmental accruals cover anticipated costs, including investigation, remediation, and operation and maintenance of clean-up sites. Our estimates are based primarily on investigations and remediation plans established by independent consultants, regulatory agencies and potentially responsible third parties. Accordingly, our estimates may change based on future developments, including new or changes in existing environmental laws or policies, differences in costs required to complete anticipated actions from estimates provided, future findings of investigation or remediation actions, or alteration to the expected remediation plans. It is our policy to realize a change in estimate once it becomes probable and can be reasonably estimated. We take into account third-party indemnification from financially viable parties in determining our accruals where there is no dispute regarding the right to indemnification. We generally do not discount our environmental accruals and do not reduce them by anticipated insurance recoveries.

In the case of contamination at offsite, third-party disposal sites, we have been notified that we are potentially responsible and have received other notices of potential liability pursuant to various environmental laws at 24 sites at which the liability has not been settled, and only 8 of which have been active in the past few years. These laws may impose liability on certain persons that are considered jointly and severally liable for the costs of investigation and remediation of hazardous substances present at these sites, regardless of fault or legality of the original disposal. These persons include the present or former owners or operators of the site and companies that generated, disposed of or arranged for the disposal of hazardous substances at the site. We are considered a “de minimis” potentially responsible party at most of the sites, and we estimate that the aggregate probable remaining liability at these sites is immaterial.

We conduct extensive environmental due diligence with respect to potential acquisitions, including environmental site assessments and such further testing as we may deem warranted. If an environmental matter is identified, we estimate the cost and either establish a liability, purchase insurance or obtain an indemnity from a financially sound seller. However, in connection with our acquisitions or dispositions, we may assume or retain significant environmental liabilities, some of which we may be unaware. The potential costs related to these environmental matters and the possible impact on future operations are uncertain due in part to the complexity of government laws and regulations and their interpretations, the varying costs and effectiveness of various clean-up technologies, the uncertain level of insurance or other types of recovery, and the questionable level of our responsibility. We record a liability when it is both probable and the amount can be reasonably estimated.

In our opinion, after considering accruals established for such purposes, remedial actions for compliance with the present laws and regulations governing the protection of the environment are not expected to have a material adverse impact, individually or in the aggregate, on our financial position, results of operations or cash flows.

Risk Management Matters

We are self-insured for certain of our workers’ compensation, automobile, product and general liability, disability and health costs, and we believe that we maintain adequate accruals to cover our retained liability. Our accruals for risk management matters are determined by us, are based on claims filed and estimates of claims incurred but not yet reported, and generally are not discounted. We consider a number of factors, including third-party actuarial valuations, when making these determinations. We maintain third-party stop-loss insurance policies to cover certain liability costs in excess of predetermined retained amounts. This insurance may be insufficient or unavailable (e.g., because of insurer insolvency) to protect us against loss exposure.

Collaborative Arrangements

Collaborative arrangements are defined as a contractual arrangement in which the parties are (1) active participants to the arrangements and (2) exposed to significant risks and rewards that depend on the commercial success of the endeavor. Costs incurred and revenues generated from transactions with third parties are required to be reported by the collaborators on the appropriate line item in their respective income statements.

We enter into consortium arrangements for certain projects within our Thermal Equipment and Services reportable segment. Under such arrangements, each consortium member is responsible for performing certain discrete items of work within the total scope of the contracted work and the consortium expires when all contractual obligations are completed. The revenues for these discrete items of work are defined in the contract with the project owner and each consortium member bearing the profitability risk associated with its own work. Our consortium arrangements typically provide that each consortium member assumes its responsible share of any damages or losses associated with the project; however, the use of a consortium arrangement typically results in joint and several liability for the consortium members. If responsibility cannot be determined or a consortium member defaults, then the consortium members are responsible according to their share of the contract value. Within our condensed consolidated financial statements, we account for our share of the revenues and profits under the consortium arrangements. As of September 29, 2012, our share of the aggregate contract value on open consortium arrangements was $269.0 (of which approximately 62% had been recognized as revenue), and the aggregate contract value on open consortium arrangements was $672.5. As of December 31, 2011, our share of the aggregate contract value on open consortium arrangements was $324.0 (of which approximately 56% had been recognized as revenue), and the aggregate contract value on open consortium arrangements was $801.1. At September 29, 2012 and December 31, 2011, we recorded liabilities of $1.7 and $1.9, respectively, representing the estimated fair value of our potential obligation under the joint and several liability provisions associated with the consortium arrangements.

U.S. Health Care Reform Legislation

In the first quarter of 2010, the Patient Protection and Affordable Care Act of 2010 (the “PPAC Act”) was enacted. The PPAC Act eliminated a portion of the federal income tax deduction available to companies that provide prescription drug benefits to retirees under Medicare Part D. We currently are evaluating other prospective effects of the PPAC Act and the related effects on our business.

INCOME TAXES

INCOME TAXES

(14) INCOME TAXES

Uncertain Tax Positions

As of September 29, 2012, we had gross unrecognized tax benefits of $85.0 (net unrecognized tax benefits of $66.0), of which $63.6, if recognized, would impact our effective tax rate from continuing operations.

We classify interest and penalties related to unrecognized tax benefits as a component of our income tax provision. As of September 29, 2012, gross accrued interest excluded from the amounts above totaled $13.4 (net accrued interest of $11.0). There were no significant penalties recorded during the three and nine months ended September 29, 2012 or October 1, 2011.

Based on the outcome of certain examinations or as a result of the expiration of statute of limitations for certain jurisdictions, we believe that within the next 12 months it is reasonably possible that our previously unrecognized tax benefits could decrease by approximately $25.0 to $35.0.

Other Tax Matters

The effective income tax rate for the quarter ended September 29, 2012 was 18.5%, compared to (29.3)% for the quarter ended October 1, 2011. The current quarter’s rate was impacted by income tax benefits of $4.2 recorded in connection with various audit settlements and statute expirations during the period and a benefit of $2.8 associated with a reduction in deferred tax liabilities resulting from the newly enacted corporate tax rates in the United Kingdom. The effective income tax rate for the three months ended October 1, 2011 was impacted favorably by an income tax benefit of $27.8 related to the release of a valuation allowance that had been recorded against our foreign tax credit carryforwards, partially offset by $6.9 of federal income taxes that were provided in connection with our plan to repatriate a portion of the earnings of a foreign subsidiary.

The effective income tax rate for the nine months ended September 29, 2012 was 25.6%, compared to 4.0% for the comparable period in 2011. The effective income tax rate for the nine months ended September 29, 2012 was impacted favorably by the tax benefits noted above for the three months ended September 29, 2012 and tax benefits of $2.5 recorded in the second quarter of 2012 in connection with various audit settlements and statute expirations. These benefits are offset partially by an incremental tax charge of $6.1 associated with the deconsolidation of the dry cooling products business in China, as the goodwill allocated to the transaction is not deductible for tax purposes. The effective income tax rate for the nine months ended October 1, 2011 was impacted by the net income tax benefits of $20.9 noted above for the quarter ended October 1, 2011, along with tax benefits of $2.5 recorded during the first half of 2011 associated with the conclusion of the Canadian appeals process and $4.5 related to the expansion of our power transformer facility in Waukesha, WI.

We perform reviews of our income tax positions on a continuous basis and accrue for potential uncertain positions when we determine that an uncertain position meets the criteria of the Income Taxes Topic of the Codification. Accruals for these uncertain tax positions are recorded in “Income taxes payable” and “Deferred and other income taxes” in the accompanying condensed consolidated balance sheets based on the expectation as to the timing of when the matters will be resolved. As events change and resolution occurs, these accruals are adjusted, such as in the case of audit settlements with taxing authorities.

The IRS concluded its audit of our 2008 and 2009 federal income tax returns during the quarter ended June 30, 2012 and issued a Revenue Agent’s Report (“RAR”). We disagree with and have protested certain adjustments within the RAR to the Appeals Office of the IRS. While resolution of these issues may result in tax liabilities that differ from the accruals established, we believe any contingencies are adequately provided for, and will not have a material adverse effect on our financial position, results of operations or liquidity. We reasonably expect to conclude this appeals process within the next twelve months. During the quarter ended September 29, 2012, the IRS initiated an audit of our 2010 and 2011 federal income tax returns. With regard to this audit, we believe any contingencies are adequately provided for.

State income tax returns generally are subject to examination for a period of three to five years after filing the respective tax returns. The impact on such tax returns of any federal changes remains subject to examination by various states for a period of up to one year after formal notification to the states. We have various state income tax returns in the process of examination, administrative appeal or litigation. We believe that any uncertain tax positions related to these examinations have been adequately provided for.

We have various foreign income tax returns under examination. Significant jurisdictions with tax examinations underway include Canada for the 2000 to 2002 and 2006 tax returns, Germany for the 2005 to 2009 tax returns and Denmark for the 2006 to 2010 tax returns. We believe that any uncertain tax positions related to these examinations have been adequately provided for.

An unfavorable resolution of one or more of the above matters could have a material adverse effect on our results of operations or cash flows in the quarter and year in which an adjustment is recorded or the tax is due or paid. As audits and examinations are still in process or we have not yet reached the final stages of the appeals process for the above matters, the timing of the ultimate resolution and any payments that may be required for the above matters cannot be determined at this time.

Upon the conclusion of our disposition activities discussed in Note 3, we may recognize an additional income tax provision or benefit, generally, as part of discontinued operations.

- Definition

FAIR VALUE

9 Months Ended

Sep. 29, 2012

FAIR VALUE

FAIR VALUE

(15) FAIR VALUE

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In the absence of active markets for the identical assets or liabilities, such measurements involve developing assumptions based on market observable data and, in the absence of such data, internal information that is consistent with what market participants would use in a hypothetical transaction that occurs at the measurement date. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our market assumptions. Preference is given to observable inputs. These two types of inputs create the following fair value hierarchy:

· Level 1 — Quoted prices for identical instruments in active markets.

· Level 2 — Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.

· Level 3 — Significant inputs to the valuation model are unobservable.

There were no changes during the three and nine months ended September 29, 2012 and October 1, 2011 to the valuation techniques we use to measure asset and liability fair values on a recurring basis. There were no transfers between the three levels of the fair value hierarchy for the three and nine months ended September 29, 2012 and October 1, 2011.

The following section describes the valuation methodologies we use to measure different financial instruments at fair value on a recurring basis.

Derivative Financial Instruments

Our financial derivative assets and liabilities include FX forward contracts, FX embedded derivatives and commodity contracts, which are valued using valuation models that measure fair value using observable market inputs such as forward rates, interest rates, our own credit risk and our counterparties’ credit risks. Based on these inputs, the derivative assets and liabilities are classified within Level 2 of the valuation hierarchy. We have not made any adjustments to the inputs obtained from the independent sources. Based on our continued ability to enter into forward contracts, we consider the markets for our fair value instruments active. We primarily use the income approach, which uses valuation techniques to convert future amounts to a single present amount.

As of September 29, 2012, there had been no significant impact to the fair value of our derivative liabilities due to our own credit risk, as the related instruments are collateralized under our senior credit facilities. Similarly, there has been no significant impact to the fair value of our derivative assets based on our evaluation of our counterparties’ credit risk.

Investments in Equity Securities

Our available-for-sale securities include equity investments that are traded in active international markets. They are measured at fair value using closing stock prices from active markets and are classified within Level 1 of the valuation hierarchy. These assets had a fair market value of $3.7 and $5.2 at September 29, 2012 and December 31, 2011, respectively.

Certain of our investments in equity securities that are not readily marketable are accounted for under the fair value option, with such values determined by multidimensional pricing models. These models consider market activity based on modeling of securities with similar credit quality, duration, yield and structure. A variety of inputs are used, including benchmark yields, reported trades, non-binding broker/dealer quotes, issuer spread and reference data including market research publications. Market indicators, industry and economic events are also considered. We have not made any adjustments to the inputs obtained from the independent sources. At September 29, 2012 and December 31, 2011, these assets had a fair value of $7.6 and $7.8, respectively, which are estimated using various valuation models, including the Monte-Carlo simulation model.

Assets and liabilities measured at fair value on a recurring basis include the following as of September 29, 2012:

	Fair Value Measurements Using
	Level 1		Level 2		Level 3
Current assets — FX forward contracts, FX embedded derivatives and commodity contracts	$	—	$	2.6	$	—
Noncurrent assets — Investment in equity securities and available-for-sale securities	3.7		—		7.6
Current liabilities — FX forward contracts and FX embedded derivatives	—		4.8		—
Long-term liabilities — FX embedded derivatives	—		12.9		—

Assets and liabilities measured at fair value on a recurring basis include the following as of December 31, 2011:

	Fair Value Measurements Using
	Level 1		Level 2		Level 3
Current assets — FX embedded derivatives	$	—	$	1.2	$	—
Current assets — Investment in equity securities and available-for-sale securities	5.2		—		7.8
Current liabilities — FX forward contracts, FX embedded derivatives and commodity contracts	—		1.9		—
Long-term liabilities — FX embedded derivatives	—		14.8		—

The table below presents a reconciliation of our investment in equity securities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the nine months ended September 29, 2012 and October 1, 2011, including net unrealized losses included in earnings.

	Nine months ended
	September 29, 2012			October 1, 2011
Balance at beginning of period	$	7.8		$	8.5
Purchases	—			—
Losses included in earnings	(0.2		)	(1.3		)
Balance at end of period	$	7.6		$	7.2

During nine months ended October 1, 2011, we determined that the fair value of our SPX Heat Transfer Inc. reporting unit was less than the carrying value of its net assets (see Note 7). The fair value of SPX Heat Transfer Inc. was based upon weighting the income and market approaches, utilizing estimated cash flows and a terminal value discounted at a rate of return that reflected the relative risk of the cash flows, as well as valuation multiples derived from comparable publicly-traded companies that were applied to the historical and projected operating results of SPX Heat Transfer Inc. (unobservable inputs — Level 3). We estimated the implied fair value of SPX Heat Transfer Inc.’s goodwill, which resulted in an impairment charge related to such goodwill of $17.2 during the second quarter of 2011. In addition, we recorded an impairment charge in the second quarter of 2011 of $7.5 related to the indefinite-lived intangible assets of SPX Heat Transfer Inc., with the fair value of these intangible assets determined based on a projection of cash flows for the assets discounted at a rate of return that reflected the relative risk of the cash flows (unobservable inputs — Level 3).

The estimated fair values of other financial liabilities (excluding capital leases) not measured at fair value on a recurring basis as of September 29, 2012 and December 31, 2011 were as follows:

	September 29, 2012				December 31, 2011
	Carrying				Carrying
	Amount		Fair Value		Amount		Fair Value
Senior Notes	$	1,100.0	$	1,224.5	$	1,100.0	$	1,198.0
Term Loans	800.0		800.0		800.0		800.0
Other indebtedness	226.4		226.4		75.1		75.1

The following methods and assumptions were used in estimating the fair value of these financial instruments:

· The fair value of the senior notes and term loans was determined using Level 2 inputs within the fair value hierarchy and was based on quoted market prices for the same or similar instruments or on current rates offered to us for debt with similar maturities, subordination and credit default expectations.

· The fair value of our short-term debt approximates carrying value due primarily to the short-term nature of those instruments.

Certain of our non-financial assets and liabilities are subject to impairment analysis, including long-lived assets, indefinite-lived intangible assets and goodwill. We review the carrying amounts of such assets whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable or at least annually for indefinite-lived intangible assets and goodwill. Any resulting asset impairment would require that the instrument be recorded at its fair value. As of September 29, 2012, with the exception of non-financial assets and liabilities that were acquired as part of new business acquisitions, we did not have any non-financial assets or liabilities that are required to be measured at fair value on a recurring or non-recurring basis. See Note 3 for further details on our recent acquisitions.

The carrying amount of cash and equivalents and receivables reported in our condensed consolidated balance sheets approximates fair value due to the short maturity of those instruments.

(1)	On February 8, 2012, the lenders under our senior credit facilities agreed, with respect to the proceeds from the pending sale of our Service Solutions business, to waive the mandatory prepayments required by the senior credit facilities. The waiver requires that a portion of the proceeds from the pending sale be used to repay $325.0 of the term loans under our senior credit facilities ($300.0 for Term Loan 1 and $25.0 for Term Loan 2). As we expect the sale to close in December 2012 and to make these debt repayments at the time of the closing, we have classified $325.0 of the term loans as ‘‘Current maturities of long-term debt’’ within our condensed consolidated balance sheet as of September 29, 2012. In addition, we have allocated approximately $2.0 and $7.0 of interest expense associated with the $325.0 of expected term loan repayments to discontinued operations within our condensed consolidated statements of operations for the three and nine months ended September 29, 2012, respectively.

(2)	Under this arrangement, we can borrow, on a continuous basis, up to $130.0, as available.

(3)	Includes balances under a purchase card program of $36.9 and $40.4 at September 29, 2012 and December 31, 2011, respectively.

(4)	“Other” includes debt assumed and foreign currency translation on any debt instruments denominated in currencies other than the U.S. dollar.

- Definition

The estimated measure of the percentage by which a share price is expected to fluctuate during a period. Volatility also may be defined as a probability-weighted measure of the dispersion of returns about the mean. The volatility of a share price is the standard deviation of the continuously compounded rates of return on the share over a specified period. That is the same as the standard deviation of the differences in the natural logarithms of the stock prices plus dividends, if any, over the period.
