Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

(1) Summary of Significant Accounting Policies

Our significant accounting policies are described below, as well as in other Notes that follow.

Basis of Presentation — The consolidated financial statements include SPX Corporation's ("SPX," "our" or "we") accounts prepared in conformity with accounting principles generally accepted in the United States ("GAAP") after the elimination of intercompany transactions. Investments in unconsolidated companies where we exercise significant influence but do not have control are accounted for 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 of the entity 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.

Unless otherwise indicated, amounts provided in these Notes pertain to continuing operations only (see Note 4 for information on discontinued operations).

Restatement of Previously Reported Financial Information — Primarily during 2007 and 2008, in connection with a reorganization of certain foreign subsidiaries, an SPX foreign subsidiary (a deemed branch of SPX for U.S. income tax purposes) assumed a loan that was guaranteed by various foreign subsidiaries of SPX. In December 2013, we identified these loans and determined that they represented a deemed distribution (i.e., additional taxable income) subject to U.S. income taxes under Internal Revenue Code Section 956. In addition, we concluded that the previously unrecorded income tax liabilities associated with these intercompany loans represented misstatements in our consolidated financial statements for the years ended December 31, 2012, 2011, 2010, 2009, 2008, and 2007. Specifically, we determined that income tax expense for these years was overstated (understated) by $(1.4), $10.7, $(4.9), $(6.1), $(18.0), and $(24.8), respectively. We have evaluated the effects of these misstatements on the consolidated financial statements for each of these years in accordance with the guidance provided by SEC Staff Accounting Bulletin No. 108, codified as SAB Topic 1.N, "Considering the Effects of Prior Year Misstatements When Quantifying Misstatements in the Current Year Financial Statements," and concluded that none of these years are materially misstated. To correct these misstatements, and as permitted by SAB No. 108, we have reduced retained earnings, SPX's shareholders' equity, and total equity by $53.8 as of December 31, 2010, with an offsetting increase primarily to income taxes payable. In addition, we have decreased the income tax benefit for 2012 by $1.4 and increased the income tax benefit for 2011 by $10.7, with the offset primarily to income taxes payable, in the respective accompanying consolidated financial statements. See Note 18 for the impact of these corrections on previously reported amounts for the years ended December 31, 2012 and 2011.

There are no corrections required to the results for the first three quarters of 2013.

Pension and Postretirement — In the fourth quarter of 2013, we elected to change our accounting methods for recognizing expense associated with all of our pension and postretirement benefit plans. Historically, actuarial gains and losses in excess of 10% of the greater of the market-related value of plan assets or the plans' projected benefit obligations (the "corridor") were recognized as a component of accumulated other comprehensive income ("AOCI") within our consolidated balance sheet and, depending on the benefit plan, we amortized these gains and losses to earnings either over the remaining average service period for the active participants or the average remaining life expectancy of the inactive participants. Additionally, for our domestic qualified pension plan, we used a calculated value of plan assets reflecting changes in the fair value of plan assets over a five-year period and we applied a fair value method for our foreign pension plans. Under our new accounting methods, we recognize changes in the fair value of plan assets and actuarial gains and losses in earnings during the fourth quarter of each year as a component of net periodic benefit expense (and we no longer apply a corridor and, therefore, no longer defer any gains or losses). These new accounting methods result in changes in the fair value of plan assets and actuarial gains and losses being recognized in earnings faster than under our previous methods of accounting. We believe the new methods of accounting are preferable as these methods recognize the effects of plan investment performance, interest rate changes, and changes in actuarial assumptions as a component of earnings in the year in which they occur. These changes have been reported through retrospective application of the new accounting methods to all periods presented. The remaining components of pension/postretirement expense, primarily service and interest costs and expected return on plan assets, will continue to be recorded on a quarterly basis. See Note 10 for further discussion of our pension and postretirement benefits and Note 19 for the impact of the above changes on our consolidated financial statements for the years ended December 31, 2013, 2012 and 2011.

Foreign Currency Translation and Transactions — The financial statements of our foreign subsidiaries are translated into U.S. dollars in accordance with the Foreign Currency Matters Topic of the Financial Accounting Standards Board Codification ("Codification" or "ASC"). Balance sheet accounts are translated at the current rate at the end of each period and income statement accounts are translated at the average rate for each period. Gains and losses on foreign currency translations are reflected as a separate component of shareholders' equity and other comprehensive income (loss). Foreign currency transaction gains and losses, as well as gains and losses related to foreign currency protection contracts and currency forward embedded derivatives, are included in "Other income (expense), net," with the related net losses totaling $15.6, $12.4 and $41.4 in 2013, 2012 and 2011, respectively.

Cash Equivalents — We consider highly liquid money market investments with original maturities of three months or less at the date of purchase to be cash equivalents.

Revenue Recognition — We recognize revenues from product sales upon shipment to the customer (e.g., FOB shipping point) or upon receipt by the customer (e.g., FOB destination), in accordance with the agreed upon customer terms. Revenues from service contracts and long-term maintenance arrangements are recognized on a straight-line basis over the agreement period. Sales with FOB destination terms are primarily to power transformer industry customers. Sales to distributors with return rights are recognized upon shipment to the distributor with expected returns estimated and accrued at the time of sale. The accrual considers restocking charges for returns and in some cases the distributor must issue a replacement order before the return is authorized. Actual return experience may vary from our estimates. We recognize revenues separately for arrangements with multiple deliverables that meet the criteria for separate units of accounting as defined by the Revenue Recognition Topic of the Codification. The deliverables under these arrangements typically include hardware and software components, installation, maintenance, extended warranties and software upgrades. Amounts allocated to each element are based on its objectively determined fair value, such as the sales price of the product or service when it is sold separately, competitor prices for similar products or our best estimate. The hardware and software components are usually recognized as revenue contemporaneously, as both are required for essential functionality of the products, with the installation being recognized upon completion. Revenues related to maintenance, extended warranties and software upgrades are recognized on a pro-rata basis over the coverage period.

We offer sales incentive programs primarily to effect volume rebates and promotional and advertising allowances. These programs are only significant to one of our business units. The liability for these programs, and the resulting reduction to reported revenues, is determined primarily through trend analysis, historical experience and expectations regarding customer participation.

Amounts billed for shipping and handling are included in revenues. Costs incurred for shipping and handling are recorded in cost of products sold. Taxes assessed by governmental authorities that are directly imposed on a revenue-producing transaction between a seller and a customer are presented on a net basis (excluded from revenues) in our consolidated statements of operations.

In addition, certain of our businesses, primarily within the Flow Technology and Thermal Equipment and Services reportable segments, also recognize revenues from long-term construction/installation contracts under the percentage-of-completion method of accounting. The percentage-of-completion is measured principally by the percentage of costs incurred to date for each contract to the estimated total costs for such contract at completion. We recognize revenues for similar short-term contracts using the completed-contract method of accounting.

Provisions for any estimated losses on uncompleted long-term contracts are made in the period in which such losses are determined. In the case of customer change orders for uncompleted long-term contracts, estimated recoveries are included for work performed in forecasting ultimate profitability on certain contracts. Due to uncertainties inherent in the estimation process, it is possible that completion costs, including those arising from contract penalty provisions and final contract settlements, may be revised in the near-term. Such revisions to costs and income are recognized in the period in which the revisions are determined.

Costs and estimated earnings in excess of billings arise when revenues have been recorded but the amounts have not been billed under the terms of the contracts. These amounts are recoverable from customers upon various measures of performance, including achievement of certain milestones, completion of specified units or completion of the contract. Claims related to long-term contracts are recognized as revenue only after we have determined that collection is probable and the amount can be reliably estimated. Claims made by us involve negotiation and, in certain cases, litigation or other dispute-resolution processes. In the event we incur litigation or other dispute-resolution costs in connection with claims, such costs are expensed as incurred, although we may seek to recover these costs. Claims against us are recognized when a loss is considered probable and amounts are reasonably estimable.

We recognized $1,343.8, $1,594.7 and $1,457.5 in revenues under the percentage-of-completion method for the years ended December 31, 2013, 2012 and 2011, respectively. Costs and estimated earnings on uncompleted contracts, from their inception, and related amounts billed as of December 31, 2013 and 2012 were as follows:

	2013			2012

Costs incurred on uncompleted contracts	$	3,767.4		$	3,363.0
Estimated earnings to date		813.2			804.8


		4,580.6			4,167.8

Research and Development Costs — We expense research and development costs as incurred. We charge costs incurred in the research and development of new software included in products to expense until technological feasibility is established. After technological feasibility is established, additional eligible costs are capitalized until the product is available for general release. We amortize these costs over the economic lives of the related products and include the amortization in cost of products sold. We perform periodic reviews of the recoverability of these capitalized software costs. At the time we determine that capitalized amounts are not recoverable based on the estimated cash flows to be generated from the applicable software, we write off any unrecoverable capitalized amounts. We expensed research activities relating to the development and improvement of our products of $44.7, $46.0 and $41.1 in 2013, 2012 and 2011, respectively.

Property, Plant and Equipment — Property, plant and equipment ("PP&E") is stated at cost, less accumulated depreciation. We use the straight-line method for computing depreciation expense over the useful lives of PP&E, which do not exceed 40 years for buildings and range from 3 to 15 years for machinery and equipment. Depreciation expense, including amortization of capital leases, was $81.8, $73.5 and $59.9 for the years ended December 31, 2013, 2012 and 2011, respectively. Leasehold improvements are amortized over the life of the related asset or the life of the lease, whichever is shorter. Interest is capitalized on significant construction or installation projects. Interest capitalized during 2012 and 2011 totaled $0.5 and $1.3, respectively. No interest was capitalized during 2013.

Income Taxes — We account for our income taxes based on the requirements of the Income Taxes Topic of the Codification, which includes an estimate of the amount of taxes payable or refundable for the current year and deferred tax liabilities and assets for the future tax consequences of events that have been recognized in our consolidated financial statements or tax returns. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. We periodically assess the realizability of deferred tax assets and the adequacy of deferred tax liabilities, including the results of local, state, federal or foreign statutory tax audits or estimates and judgments used.

Derivative Financial Instruments — We use foreign currency forward contracts ("FX forward contracts") to manage our exposures to fluctuating currency exchange rates, and forward contracts to manage the exposure on forecasted purchases of commodity raw materials ("commodity contracts"). We have used interest rate protection agreements ("Swaps") to manage our exposures to fluctuating interest rate risk on variable rate debt. Derivatives are recorded on the balance sheet and measured at fair value. For derivatives designated as hedges of the fair value of assets or liabilities, the changes in fair values of both the derivatives and the hedged items are recorded in current earnings. For derivatives designated as cash flow hedges, the effective portion of the changes in fair value of the derivatives is recorded in AOCI and subsequently recognized in earnings when the hedged items impact earnings. Changes in the fair value of derivatives not designated as hedges, and the ineffective portion of cash flow hedges, are recorded in current earnings. We do not enter into financial instruments for speculative or trading purposes.

For those transactions that are designated as cash flow hedges, on the date the derivative contract is entered into, we document our hedge relationship, including identification of the hedging instruments and the hedged items, as well as our risk management objectives and strategies for undertaking the hedge transaction. We also assess, both at inception and quarterly thereafter, whether such derivatives are highly effective in offsetting changes in the fair value of the hedged item. See Notes 13 and 16 for further information.

Cash flows from hedging activities are included in the same category as the items being hedged, which is primarily operating activities.

Use of Estimates

Use of Estimates

(2) Use of Estimates

The preparation of our consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues (e.g., our percentage-of-completion estimates described above) and expenses during the reporting period. We evaluate these estimates and judgments on an ongoing basis and base our estimates on experience, current and expected future conditions, third-party evaluations and various other assumptions that we believe are reasonable under the circumstances. The results of these estimates form the basis for making judgments about the carrying values of assets and liabilities as well as identifying and assessing the accounting treatment with respect to commitments and contingencies. Actual results may differ from the estimates and assumptions used in the consolidated financial statements and related notes.

Listed below are certain significant estimates and assumptions used in the preparation of our consolidated financial statements. Certain other estimates and assumptions are further explained in the related notes.

Accounts Receivable Allowances — We provide allowances for estimated losses on uncollectible accounts based on our historical experience and the evaluation of the likelihood of success in collecting specific customer receivables. In addition, we maintain allowances for customer returns, discounts and invoice pricing discrepancies, with such allowances primarily based on historical experience. Summarized below is the activity for these allowance accounts.

	Year ended December 31,

	2013			2012			2011
Balance at beginning of year	$	49.9		$	40.7		$	43.8
Allowances provided		23.1			26.2			16.0
Write-offs, net of recoveries, credits issued and other		(26.7	)		(17.0	)		(19.1	)


Balance at end of year	$	46.3		$	49.9		$	40.7

Inventory — We estimate losses for excess and/or obsolete inventory and the net realizable value of inventory based on the aging and historical utilization of the inventory and the evaluation of the likelihood of recovering the inventory costs based on anticipated demand and selling price.

Impairment of Long-Lived Assets and Intangible Assets Subject to Amortization — We continually review whether events and circumstances subsequent to the acquisition of any long-lived assets, or intangible assets subject to amortization, have occurred that indicate the remaining estimated useful lives of those assets may warrant revision or that the remaining balance of those assets may not be fully recoverable. If events and circumstances indicate that the long-lived assets should be reviewed for possible impairment, we use projections to assess whether future cash flows on an undiscounted basis related to the assets are likely to exceed the related carrying amount. We will record an impairment charge to the extent that the carrying value of the assets exceed their fair values as determined by valuation techniques appropriate in the circumstances, which could include the use of similar projections on a discounted basis.

In determining the estimated useful lives of definite-lived intangibles, we consider the nature, competitive position, life cycle position, and historical and expected future operating cash flows of each acquired asset, as well as our commitment to support these assets through continued investment and legal infringement protection.

Goodwill and Indefinite-Lived Intangible Assets — We test goodwill and indefinite-lived intangible assets for impairment annually during the fourth quarter and continually assess whether a triggering event has occurred to determine whether the carrying value exceeds the implied fair value. The fair value of reporting units is based generally on discounted projected cash flows, but we also consider factors such as comparable industry price multiples. We employ cash flow projections that we believe to be reasonable under current and forecasted circumstances, the results of which form the basis for making judgments about the carrying values of the reported net assets of our reporting units. Many of our businesses closely follow changes in the industries and end markets that they serve. Accordingly, we consider estimates and judgments that affect the future cash flow projections, including principal methods of competition, such as volume, price, service, product performance and technical innovations, as well as estimates associated with cost reduction initiatives, capacity utilization and assumptions for inflation and foreign currency changes. Actual results may differ from these estimates under different assumptions or conditions. See Note 8 for further information, including discussion of impairment charges recorded in 2013, 2012 and 2011.

Accrued Expenses — We make estimates and judgments in establishing accruals as required under GAAP. Summarized in the table below are the components of accrued expenses at December 31, 2013 and 2012.

	December 31,

	2013		2012
Employee benefits	$	214.7	$	183.0
Unearned revenue⁽¹⁾		460.7		469.1
Warranty		42.1		49.6
Other⁽²⁾		271.7		278.3


Total	$	989.2	$	980.0

⁽¹⁾: Unearned revenue includes billings in excess of costs and estimated earnings on uncompleted contracts accounted for under the percentage-of-completion method of revenue recognition, customer deposits and unearned amounts on service contracts.
⁽²⁾: Other consists of various items including, among other items, accrued legal costs, interest, restructuring costs and dividends payable, none of which is individually material.

Legal — It is our policy to accrue for estimated losses from legal actions or claims when events exist that make the realization of the losses probable and they can be reasonably estimated. We do not discount legal obligations or reduce them by anticipated insurance recoveries.

Environmental Remediation Costs — We expense costs incurred to investigate and remediate environmental issues unless they extend the economic useful lives of related assets. We record liabilities when it is probable that an obligation has been incurred and the amounts can be reasonably estimated. 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. We generally do not discount environmental obligations or reduce them by anticipated insurance recoveries.

Self-Insurance — We are self-insured for certain of our workers' compensation, automobile, product, general liability, disability and health costs, and we maintain adequate accruals to cover our retained liabilities. Our accruals for self-insurance liabilities are based on claims filed and an estimate 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; however, this insurance may be insufficient or unavailable (e.g., because of insurer insolvency) to protect us against potential loss exposures. The key assumptions considered in estimating the ultimate cost to settle reported claims and the estimated costs associated with incurred but not yet reported claims include, among other things, our historical and industry claims experience, trends in health care and administrative costs, our current and future risk management programs, and historical lag studies with regard to the timing between when a claim is incurred and reported.

Warranty — In the normal course of business, we issue product warranties for specific products and provide for the estimated future warranty cost in the period in which the sale is recorded. We provide for the estimate of warranty cost based on contract terms and historical warranty loss experience that is periodically adjusted for recent actual experience. Because warranty estimates are forecasts that are based on the best available information, claims costs may differ from amounts provided. In addition, due to the seasonal fluctuations at certain of our businesses, the timing of warranty provisions and the usage of warranty accruals can vary period to period. We make adjustments to initial obligations for warranties as changes in the obligations become reasonably estimable. The following is an analysis of our product warranty accrual for the periods presented:

	Year ended December 31,

	2013			2012			2011
Balance at beginning of year	$	59.7		$	55.7		$	46.9
Acquisitions		—			3.7			7.7
Provisions		30.7			24.7			20.9
Usage		(35.6	)		(24.4	)		(19.8	)


Balance at end of year		54.8			59.7			55.7
Less: Current portion of warranty		42.1			49.6			45.6


Non-current portion of warranty	$	12.7		$	10.1		$	10.1

Income Taxes — We perform reviews of our income tax positions on a continuous basis and accrue for potential uncertain tax positions in accordance with the Income Taxes Topic of the Codification. Accruals for these uncertain tax positions are classified as "Income taxes payable" and "Deferred and other income taxes" in the accompanying consolidated balance sheets based on an expectation as to the timing of when the matter will be resolved. As events change or resolutions occur, these accruals are adjusted, such as in the case of audit settlements with taxing authorities. These reviews also entail analyzing the realization of deferred tax assets. When we believe that it is more likely than not that we will not realize a benefit for a deferred tax asset, we establish a valuation allowance against it. For tax positions where it is more likely than not that a tax benefit will be sustained, we record the largest amount of tax benefit with a greater than 50% likelihood of being realized upon ultimate settlement with a taxing authority, assuming such authority has full knowledge of all relevant information.

Employee Benefit Plans — Defined benefit plans cover a portion of our salaried and hourly employees, including certain employees in foreign countries. As discussed in Note 1, in the fourth quarter of 2013, we elected to change our accounting methods for recognizing changes in the fair value of plan assets and actuarial gains and losses associated with our pension and postretirement benefit plans. Under our new preferable accounting methods, we recognize changes in the fair value of plan assets and actuarial gains and losses in earnings during the fourth quarter of each year as a component of net periodic benefit expense. These changes have been reported through retrospective application of the new accounting methods to all periods reported. The remaining components of pension/postretirement expense, primarily service and interest costs and expected return on plan assets, will be recorded on a quarterly basis. See Note 10 for further discussion of our pension and postretirement benefits and Note 19 for the impact of the above changes on our consolidated financial statements for the years ended December 31, 2013, 2012 and 2011.

We derive pension expense from an actuarial calculation based on the defined benefit plans' provisions and our assumptions regarding discount rate and rate of increase in compensation levels. We determine the discount rate for our more significant U.S. plans by matching the expected projected benefit obligation cash flows of the plans to a yield curve that is representative of long-term, high-quality (rated AA or higher) fixed income debt instruments as of the measurement date. For our other plans, we determine the discount rate based on representative bond indices. The rate of increase in compensation levels is established based on our expectations of current and foreseeable future increases in compensation. We also consult with independent actuaries in determining these assumptions.

- Definition

Provides an entity's explanation that the preparation of financial statements in conformity with generally accepted accounting principles requires the use of management estimates. Estimates used in the determination of carrying amounts of assets or liabilities, or in disclosure of gain or loss contingencies should be disclosed if known information available prior to issuance of the financial statements indicates that both of these criteria are met: (1) It is at least reasonably possible that the estimate of the effect on the financial statements of a condition, situation, or set of circumstances that existed at the date of the financial statements will change in the near term (less than one year from the date of issuance) due to one or more future confirming events, and (2) The effect of the change would be material to the financial statements. The disclosure should indicate the nature of the uncertainty and include an indication that it is at least reasonably possible that a change in the estimate will occur in the near term. Disclosure of the factors that cause the estimate to be sensitive to change also is encouraged. Entities also may identify those areas that are subject to significant estimates.

New Accounting Pronouncements	12 Months Ended
New Accounting Pronouncements	Dec. 31, 2013
New Accounting Pronouncements
New Accounting Pronouncements	(3) New Accounting Pronouncements The following is a summary of new accounting pronouncements that 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 was 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 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 Topic 350 of the Codification. If entities determine, 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 was effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. We adopted the guidance for the year ended December 31, 2012, with no material impact on our consolidated financial statements. In December 2011, and as amended in January 2013, the FASB issued disclosure guidance relating to offsetting, whereby entities are required to disclose both gross and net information about both instruments and transactions eligible for offset in the statement of financial position and instruments and transactions subject to a master netting arrangement or similar agreement. 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 guidance applies to (i) recognized financial and derivative instruments offset in accordance with either the Balance Sheet or Derivatives and Hedging topics of the Codification and (ii) 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 guidance was effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods, and must be applied retrospectively for all comparative periods presented. We adopted this guidance on January 1, 2013, with the required disclosures included in Note 13. In July 2012, the FASB issued an amendment to guidance relating 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, 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 was effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. We adopted this guidance on January 1, 2013, with no material impact on our consolidated financial statements. In February 2013, the FASB issued an amendment to guidance relating to the reporting of reclassifications out of AOCI. This guidance requires companies to present, in one place, information about significant amounts reclassified from AOCI. In addition, for significant items reclassified out of AOCI to net income in their entirety during the reporting period, companies must report the effect of such reclassifications on the respective line items in the statement of operations. For amounts not required to be reclassified to net income in their entirety, companies must reference the disclosures that provide additional detail about those amounts. This amendment was effective for interim and annual reporting periods beginning after December 15, 2012, and must be applied prospectively. We adopted this guidance on January 1, 2013, with the required disclosures included in Note 15. In March 2013, the FASB issued an amendment to guidance to resolve the diversity in practice relating to a parent entity's accounting for the cumulative translation adjustment ("CTA") upon derecognition of foreign subsidiaries or groups of assets. The amendment requires that any CTA related to the parent entity's investment in a foreign entity be released into earnings when a sale or transfer of the foreign subsidiary or group of assets results in the complete or substantially complete liquidation of the foreign entity. This amendment is effective for interim and annual reporting periods beginning after December 15, 2013, and must be applied prospectively. We will adopt this guidance in 2014 and do not expect the adoption to have a material impact on our consolidated financial statements. In July 2013, the FASB issued an amendment to guidance to resolve the diversity in practice in the presentation of unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward (collectively, a "carryforward") exists. An unrecognized tax benefit, or portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for the carryforward, except to the extent (i) the carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or (ii) the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose. In these cases, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. This amendment applies to all entities that have unrecognized tax benefits when a carryforward exists at the reporting date. This amendment is effective for interim and annual reporting periods beginning after December 15, 2013 and must be applied prospectively to all unrecognized tax benefits that exist at the effective date, with retrospective application permitted. We will adopt this guidance in 2014 and do not expect the adoption to have a material impact on our consolidated financial statements.

Acquisitions, Discontinued Operations and Formation of Shanghai Electric JV

Acquisitions, Discontinued Operations and Formation of Shanghai Electric JV

(4) Acquisitions, Discontinued Operations and Formation of Shanghai Electric JV

We use acquisitions as a part of our strategy to gain access to customer relationships and new technology, expand our geographical reach, penetrate new markets and leverage our existing product, market, manufacturing and technical expertise. Further, 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 continuous review, we determined that certain of our businesses would be better strategic fits with other companies or investors. Acquisitions and divestitures for the years ended December 31, 2013, 2012 and 2011 are described below.

The consolidated statements of operations include the results of each acquired business since the date of acquisition. The assets acquired and liabilities assumed are recorded at estimates of fair values as determined by us based on information available at the acquisition date. We consider a number of factors, including third-party valuations or appraisals, when making these determinations. We will recognize additional assets or liabilities if new information is obtained during the measurement period about facts and circumstances that existed as of the acquisition date that, if known, would have resulted in the recognition of those assets and liabilities as of that date. The measurement period will not exceed one year from the acquisition date. Refer to Note 8 for additional disclosure on the purchase price adjustments of the following acquisitions.

There were no acquisitions in 2013.

Acquisition — 2012

On March 21, 2012, our Flow Technology reportable segment 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. The pro forma effects of the acquisition of Seital were not material, individually or in the aggregate, to our consolidated results of operations.

Acquisitions — 2011

On December 22, 2011, our Flow Technology reportable segment completed the acquisition of 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 included 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 GBP 0.0 or more than GBP 250.0. No liability for an earn-out payment has been provided in the accompanying balance sheets because, based on actual operating results for 2012, we do not believe Clyde Union achieved the required minimum Annual 2012 Group EBITDA.

We financed the acquisition with available cash and committed senior secured financing. The sellers of Clyde Union also contributed GBP 25.0 of cash to the acquired business at the time of sale.

The following is a summary of the recorded fair values of the assets acquired and liabilities assumed for Clyde Union at the date of acquisition, and reflects acquisition accounting adjustments subsequently recorded:


Assets acquired:
Current assets, including cash and equivalents of $44.3	$	342.1
Property, plant and equipment		88.4
Goodwill		373.7
Intangible assets		374.6
Other assets		25.1


Total assets acquired		1,203.9


Liabilities assumed:
Current liabilities		291.9
Other long-term liabilities		150.1


Total liabilities assumed		442.0


Noncontrolling interest		(5.1	)


Net assets acquired	$	767.0

The identifiable intangible assets acquired consist of customer relationships, trademarks, technology, and customer lists of $234.4, $76.8, $60.1 and $3.3, respectively. The customer relationships, technology assets, and customer lists are being amortized over 30, 27, and 2 years, respectively.

The qualitative factors that comprise the recorded goodwill include expected synergies from combining our existing and Clyde Union's operations, expected market growth for existing Clyde Union operations as well as other factors. We expect none of this goodwill to be deductible for income tax purposes.

We acquired gross receivables of $148.9, which had a fair value on acquisition date of $145.0 based on our estimates of cash flows expected to be recovered.

The following unaudited pro forma information presents our after-tax results of operations 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 charges or cost reductions related to restructuring actions undertaken at Clyde Union since the acquisition. These pro forma results of operations have been prepared for comparative purposes only and include the following adjustments to historical results for the period presented, in each case adjusted for the applicable income tax impact:

•

Additional depreciation and amortization expense of $5.5 associated with the fair value adjustments to the acquired Clyde Union property, plant and equipment and intangible assets.

•

The elimination of interest expense of $17.8 related to the portion of Clyde Union's long-term debt that was paid-off at the time of the acquisition.

•

The addition of interest expense of $19.0 associated with the term loans that were drawn down in order to finance the Clyde Union acquisition.

•

The elimination of rent expense of $2.1 associated with a facility in Scotland that had been leased by Clyde Union and that we purchased on December 23, 2011.

•

The elimination of $34.6 in charges incurred in 2011 associated with the foreign currency protection agreements that we entered into to hedge the Clyde Union purchase price.

•

The elimination of $7.4 of transaction fees incurred in 2011 in connection with the acquisition (Buyer — $5.6 and Seller — $1.8).

•

A reduction in bonding costs of $5.9 for Clyde Union due to more favorable rates under our senior credit facilities.

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. No liability for an earn-out payment has been provided in the accompanying consolidated balance sheets because we do not believe e&e achieved the criteria required during the earn-out period. 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. Murdoch had revenues of approximately $13.0 in the twelve months prior to the date of acquisition.

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

Discontinued Operations

We report businesses or asset groups as discontinued operations when, among other things, we terminate the operations of the business or asset group, commit to a plan to divest the business or asset group or we actively begin marketing the business or asset group, and the sale of the business or asset group is deemed probable within the next twelve months. During the third quarter of 2013, we committed to a plan to divest certain non-strategic businesses that were previously reported within Industrial Products and Services and Other. These businesses have been reported, for all periods presented, as discontinued operations within the accompanying consolidated financial statements. We are actively pursuing the sales of these businesses and anticipate that the sales will be completed during 2014.

In addition, the following businesses, which have been sold or for which operations have been terminated, also met these requirements and therefore have been reported as discontinued operations for all periods presented:

Business

Broadcast Antenna System business ("Dielectric")	Q2 2013	Q2 2013
Crystal Growing business ("Kayex")	Q1 2013	Q1 2013
TPS Tianyu Equipment Co., Ltd. ("Tianyu")	Q4 2012	Q4 2012
Weil-McLain (Shandong) Cast-Iron-Boiler Co., Ltd. ("Weil-McLain Shandong")	Q4 2012	Q4 2012
SPX Service Solutions ("Service Solutions")	Q1 2012	Q4 2012

Dielectric — We sold assets of the business during 2013 for cash consideration of $4.7, resulting in a gain of less than $0.1.

Kayex — We closed the business during 2013. We recorded a gain, net of taxes, of $1.3 during 2013 associated primarily with a gain on the sale of a perpetual license related to certain of the business's intangible assets, which was partially offset by a loss related to severance costs and asset impairment charges. Proceeds from the sale of the perpetual license totaled $6.9.

Tianyu — Sold for cash consideration of one Chinese Yuan ("CNY") (exclusive of cash transferred with the business of $1.1), resulting in a loss, net of taxes, of $1.8 during 2012.

Weil-McLain Shandong — Sold for cash consideration of $2.7 (exclusive of cash transferred with the business of $3.1), resulting in a gain, net of taxes, of $2.2 during 2012. During 2013, we received $1.1 associated with the working capital settlement and reduced the net gain by $0.4.

Service Solutions — Sold to Robert Bosch GmbH for cash consideration of $1,134.9, resulting in a gain, net of taxes, of $313.4 during 2012. During 2013, we received $0.8 associated with the working capital settlement and reduced the net gain by $0.3, associated primarily with the working capital settlement and revisions to income tax and other retained liabilities related to the sale.

In addition to the businesses discussed above, we recognized net gains (losses) of $(4.6), $(0.4) and $0.3 during 2013, 2012 and 2011, respectively, resulting from adjustments to gains/losses on dispositions of businesses discontinued prior to 2011.

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 with the buyers, an arbitration or other dispute-resolution process. Final agreement of the working capital figures with the buyers 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 2013, 2012 and 2011, income from discontinued operations and the related income taxes are shown below:

Formation of Shanghai Electric JV

On December 30, 2011, we and Shanghai Electric Group Co., Ltd. established Shanghai Electric — SPX Engineering & Technologies Co., Ltd. (the "Shanghai Electric JV"), a joint venture supplying 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 CNY 96.7, with CNY 51.5 received in January 2012, CNY 25.8 received in December 2012, and the remaining CNY 19.4 received in 2013. In addition, we have licensed our dry cooling and moisture separator reheater technologies to the joint venture, for which we are receiving a royalty. We also are continuing 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 in January 2012. We determined that this transaction met the deconsolidation criteria of the Consolidation Topic of the Codification, and, thus, recorded a gain for the transaction equal to the estimated fair value of our investment in the joint venture plus any consideration received, less the carrying value of assets contributed and sold to the joint venture. We recorded the net gain associated with this transaction of $20.5 in the first quarter of 2012, with the gain included in "Other income (expense), net."

The Shanghai Electric JV's results of operations and our equity earnings in this investment, as included in our consolidated statements of operations, were not material in 2013 and 2012.

(5) Information on Reportable Segments and Other Operating Segments

We are a global supplier of highly specialized, engineered solutions with operations in over 35 countries and sales in over 150 countries around the world. Many of our products and innovative solutions play a role in helping to meet rising global demand for power and energy and processed foods and beverages, particularly in emerging markets. In 2013, an estimated 30% of our revenues were from sales into emerging markets. Our key products include processing systems and equipment for the food and beverage industry, reciprocating pumps used in oil and gas processing, power transformers used by utility companies, and cooling systems for power plants.

We aggregate certain of our operating segments into our two reportable segments, Flow Technology and Thermal Equipment and Services, while 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 and Other. The operating segments in this "All Other" category generally serve industrial end-markets. Industrial Products and Services and Other 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, pension 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.

Revenues by reportable segment and our other operating segments and geographic area represent sales to unaffiliated customers, and no one customer or group of customers that, to our knowledge, are under common control accounted for more than 10% of our consolidated revenues for any period presented. Intercompany revenues among reportable segments and our other operating segments are not significant. Identifiable assets by reportable segment and for the other operating segments are those used in the respective operations of each. General corporate assets are principally cash, pension assets, deferred tax assets, certain prepaid expenses, fixed assets, and our 44.5% interest in the EGS Electrical Group, LLC and subsidiaries ("EGS") joint venture. See Note 9 for financial information relating to EGS.

(6) Special Charges, Net

As part of our business strategy, we periodically right-size and consolidate operations to improve long-term results. Additionally, from time to time, we alter our business model to better serve customer demand, discontinue lower-margin product lines and rationalize and consolidate manufacturing capacity. Our restructuring and integration decisions are based, in part, on discounted cash flows and are designed to achieve our goals of increasing outsourcing, reducing structural footprint and maximizing profitability. As a result of our strategic review process, we recorded net special charges of $32.3 in 2013, $23.4 in 2012 and $21.0 in 2011. These net special charges were primarily related to restructuring initiatives to consolidate manufacturing and sales facilities, reduce workforce, and rationalize certain product lines, as well as asset impairment charges.

The components of the charges have been computed based on actual cash payouts, including severance and other employee benefits based on existing severance policies, local laws, and other estimated exit costs, and our estimate of the realizable value of the affected tangible and intangible assets.

Impairments of long-lived assets, including amortizable intangibles, which represent non-cash asset write-downs, typically arise from business restructuring decisions that lead to the disposition of assets no longer required in the restructured business. For these situations, we recognize a loss when the carrying amount of an asset exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. Fair values for assets subject to impairment testing are determined primarily by management, taking into consideration various factors including third-party appraisals, quoted market prices and previous experience. If an asset remains in service at the decision date, the asset is written down to its fair value and the resulting net book value is depreciated over its remaining economic useful life. When we commit to a plan to sell an asset, including the initiation of a plan to locate a buyer, and it is probable that the asset will be sold within one year based on its current condition and sales price, depreciation of the asset is discontinued and the asset is classified as an asset held for sale. The asset is written down to its fair value less any selling costs.

Liabilities for exit costs, including, among other things, severance, other employee benefit costs, and operating lease obligations on idle facilities, are measured initially at their fair value and recorded when incurred.

With the exception of certain multi-year operating lease obligations and other contractual obligations, which are not material to our consolidated financial statements, we anticipate that the liabilities related to restructuring actions will be paid within one year from the period in which the action was initiated.

Special charges for the years ended December 31, 2013, 2012 and 2011 are described in more detail below and in the applicable sections that follow.

Flow Technology reportable segment — Charges for 2013 related primarily to severance costs associated with (i) restructuring initiatives at Clyde Union locations primarily in the U.K. and the U.S. and (ii) the operational realignment of the segment's reporting structure. These actions were taken primarily to reduce the cost base of Clyde Union, as we continue to integrate the business into our Flow Technology reportable segment, and to further align the segment's operational structure to its key end markets. Once completed, these activities are expected to result in the termination of approximately 480 employees. Charges for 2013 also included asset impairment charges of $1.7 related primarily to facilities that will be exited in the U.S., Denmark and the U.K.

Thermal Equipment and Services reportable segment — Charges for 2013 related primarily to severance and other costs associated with restructuring actions at our Balcke Duerr and dry cooling businesses in Germany. These actions were taken to reduce the cost base of the businesses in response to reduced demand for nuclear power products and services in Europe. Once completed, these activities are expected to result in the termination of approximately 300 employees.

Industrial Products and Services and Other — Charges for 2013 related primarily to costs associated with restructuring initiatives at various locations in the U.S. These actions resulted in the termination of approximately 40 employees.

Corporate — Charges for 2013 related primarily to costs associated with the early termination of two building leases and an asset impairment charge of $0.3.

Expected charges still to be incurred under actions approved as of December 31, 2013 are approximately $2.0.

Flow Technology reportable segment — Charges for 2012 related primarily to cost reduction initiatives for the segment's components business in Europe and at locations in Canada and Denmark, as well as costs associated with the relocation of the segment's America's Shared Service Center from Des Plaines, IL to Charlotte, NC, the integration of Clyde Union, and the reorganization of the segment's food and beverage systems business, including asset impairment charges of $0.9. These activities resulted in the termination of 271 employees.

Thermal Equipment and Services reportable segment — Charges for 2012 related primarily to costs associated with restructuring initiatives at various locations in China and Europe, including asset impairment charges totaling $1.6, and severance costs associated with transferring certain functions of our boiler and heating products business to a location in Chicago, IL. These activities resulted in the termination of 195 employees.

Industrial Products and Services and Other — Charges for 2012 related primarily to costs associated with the closure of a location within our portable cable and pipe locator business.

Corporate — Charges for 2012 included a gain of $4.8 on the sale of land rights in Shanghai, China, for which the related costs previously had been written-off. This gain was offset partially by costs associated with consolidating certain corporate functions and our legal entity reduction initiative.

Inventories include material, labor and factory overhead costs and are reduced, when necessary, to estimated net realizable values. Certain domestic inventories are valued using the last-in, first-out ("LIFO") method. These inventories were approximately 19% and 17% of total inventory at December 31, 2013 and 2012, respectively. Other inventories are valued using the first-in, first-out ("FIFO") method. During 2013 and 2012, inventory reduction at certain businesses resulted in a liquidation of LIFO inventory quantities carried at lower costs prevailing in prior years, the effect of which increased operating income by approximately $0.2 and $0.1 during the years ended December 31, 2013 and 2012, respectively.

Amortization expense was $33.0, $34.1 and $22.8 for the years ended December 31, 2013, 2012 and 2011, respectively. Estimated amortization expense related to these intangible assets is $31.1 in 2014, $30.7 in 2015, $30.4 in 2016, $30.0 in 2017, and $29.9 in 2018.

At December 31, 2013, the net carrying value of intangible assets with determinable lives consisted of $437.6 in the Flow Technology reportable segment, $47.3 in the Thermal Equipment and Services reportable segment, and $8.0 in Industrial Products and Services and Other. Trademarks with indefinite lives consisted of $287.1 in the Flow Technology reportable segment, $126.3 in the Thermal Equipment and Services reportable segment, and $18.4 in Industrial Products and Services and Other.

Consistent with the requirements of the Intangible — Goodwill and Other Topic of the Codification, the fair values of our reporting units generally are estimated using discounted cash flow projections that we believe to be reasonable under current and forecasted circumstances, the results of which form the basis for making judgments about carrying values of the reported net assets of our reporting units. Other considerations are also incorporated, including comparable industry price multiples. Many of our reporting units closely follow changes in the industries and end markets that they serve. Accordingly, we consider estimates and judgments that affect the future cash flow projections, including principal methods of competition such as volume, price, service, product performance and technical innovations and estimates associated with cost improvement initiatives, capacity utilization and assumptions for inflation and foreign currency changes. Any significant change in market conditions and estimates or judgments used to determine expected future cash flows that indicate a reduction in carrying value may give rise to impairment in the period that the change becomes known.

We perform our annual goodwill impairment testing during the fourth quarter in conjunction with our annual financial planning process, with such testing based primarily on events and circumstances existing as of the end of the third quarter. In addition, we test goodwill for impairment on a more frequent basis if there are indications of potential impairment. Based on our annual goodwill impairment testing in 2013, we determined that the estimated fair value of each of our reporting units exceeds the carrying value of their respective net assets by at least 10%.

We perform our annual trademarks impairment testing during the fourth quarter, or on a more frequent basis if there are indications of potential impairment. The fair values of our trademarks are determined by applying estimated royalty rates to projected revenues, with the resulting cash flows discounted at a rate of return that reflects current market conditions. During 2013, we recorded impairment charges of $6.7 related to trademarks of certain businesses within our Flow Technology reportable segment. Other changes in the gross values of trademarks and other identifiable intangible assets related primarily to foreign currency translation.

In connection with our annual goodwill impairment testing in 2012, our analysis indicated that the estimated fair value of our Cooling reporting unit was below the carrying value of its net assets. As a result, we estimated the implied fair value of Cooling's goodwill, which resulted in an impairment charge related to such goodwill of $270.4. The impairment charge of $270.4 was composed of (i) a $125.8 difference between the estimated fair value of Cooling compared to the carrying value of its net assets and (ii) an allocation to certain tangible and intangible assets of $144.6 for the estimated increases in fair value for these assets solely for purposes of applying the impairment provisions of the Intangible — Goodwill and Other Topic of the Codification.

In addition to the goodwill impairment charge of $270.4, we recorded an impairment charge of $11.0 in 2012 related to certain long-term assets of our Cooling reporting unit. Lastly, we recorded impairment charges of $4.5 in 2012 related to trademarks for two other businesses within our Thermal Equipment and Services reportable segment.

In the second quarter of 2011, our SPX Heat Transfer reporting unit within our Thermal Equipment and Services reportable segment experienced a decline in its revenues and profitability, furthering a trend that began late in the first quarter of 2011. As a result, during the second quarter of 2011, we updated the projection of future discounted cash flows for SPX Heat Transfer, which indicated that 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's goodwill ($17.2) and indefinite-lived intangible assets ($7.5). In connection with our annual goodwill impairment testing during the fourth quarter of 2011, and in consideration of a further decline in SPX Heat Transfer's revenue and profitability, we determined that the remaining goodwill ($3.6) of the reporting unit was impaired and, thus, recorded an impairment charge of $3.6 during the fourth quarter of 2011.

Investment in Joint Venture

(9) Investment in Joint Venture

As of December 31, 2013, we had a joint venture, EGS, with Emerson Electric Co., in which we held a 44.5% interest. Emerson Electric Co. controlled and operated the joint venture. EGS operates primarily in the United States, Brazil, Canada and France and is engaged in the manufacture of electrical fittings, hazardous location lighting and power conditioning products. We accounted for our investment using the equity method, on a three-month lag basis, and we typically received our share of the joint venture's earnings in cash dividends paid quarterly. EGS's results of operations and selected other information for its fiscal years ended September 30, 2013, 2012 and 2011 were as follows:

	2013		2012		2011

Revenues	$	517.5	$	527.0	$	495.3
Gross profit		223.3		221.9		201.5
Income from continuing operations		89.4		87.9		63.7

Dividends received by SPX		30.3		35.2		29.4
Undistributed earnings attributable to SPX Corporation		20.0		8.4		4.6
SPX's equity earnings in EGS		41.9		39.0		28.7

Condensed balance sheet information of EGS as of September 30, 2013 and 2012 was as follows:

	2013		2012

Current assets	$	180.4	$	183.5
Non-current assets		336.4		339.6
Current liabilities		108.0		116.9
Non-current liabilities		24.0		33.0

The carrying value of our investment in EGS was $81.8 and $73.5 at December 31, 2013 and 2012, respectively, and is recorded in "Other assets" in our consolidated balance sheets. We contributed non-monetary assets to EGS upon its formation. We recorded these contributed assets at their historical cost while EGS recorded these assets at their fair value. As a result of this basis difference in the goodwill recorded by EGS upon formation, our investment in EGS is less than our proportionate share of EGS's net assets, with such difference totaling $89.4 at December 31, 2013.

On January 7, 2014, we completed the sale of our 44.5% interest in EGS to Emerson Electric Co. for $574.1. As a result of the sale, we will record a gain, net of tax, of approximately $300.0 in our first quarter 2014 results of operations.

The financial position, results of operations and cash flows of our other equity method investments are not material, individually or in the aggregate, in relation to our consolidated financial statements.

Employee Benefit Plans

Employee Benefit Plans

(10) Employee Benefit Plans

Overview — Defined benefit pension plans cover a portion of our salaried and hourly paid employees, including certain employees in foreign countries. Beginning in 2001, we discontinued providing these pension benefits generally to newly hired employees. In addition, we no longer provide service credits to certain active participants. Of the U.S. employees covered by a defined benefit pension plan and actively accruing a benefit, most are covered by an account balance plan or are part of a collectively bargained plan.

We have domestic postretirement plans that provide health and life insurance benefits to certain retirees and their dependents. Beginning in 2003, we discontinued providing these postretirement benefits generally to newly hired employees. Some of these plans require retiree contributions at varying rates. Not all retirees are eligible to receive these benefits, with eligibility governed by the plan(s) in effect at a particular location.

The plan year-end date for all our plans is December 31.

Transfer of Retiree Pension Obligations and Lump-Sum Offer — On November 12, 2013, we executed an agreement to transfer obligations for monthly pension payments to retirees under the SPX U.S. Pension Plan (the "Plan") to Massachusetts Mutual Life Insurance Company ("Mass Mutual"). Under the agreement, Mass Mutual has irrevocably assumed the obligation to make future pension payments to the approximate 16,000 retirees of the Plan beginning in April 2014. The Plan paid Mass Mutual $663.7 to assume obligations totaling approximately $609.0. Additionally, during a designated election period in the first quarter of 2014, we are offering approximately 7,500 eligible former employees under the Plan a voluntary single lump-sum payment option in lieu of a future pension benefit under the Plan.

Change in Accounting Methods — As further described in Note 1, we elected to change our accounting methods for recognizing changes in the fair value of plan assets and actuarial gains and losses associated with our pension and postretirement benefit plans. Accordingly, we have made revisions to previously reported amounts, including net periodic benefit cost, AOCI, and retained earnings. See Note 19 for the impact of the change in accounting methods on our consolidated financial statements for the years ended December 31, 2013, 2012 and 2011.

Defined Benefit Pension Plans

Plan assets — Our investment strategy is based on the long-term growth of principal while mitigating overall risk to ensure that funds are available to pay benefit obligations. The domestic plan assets are invested in a broad range of investment classes, including domestic and international equities, fixed income securities and other investments. We engage various investment managers who are regularly evaluated on long-term performance, adherence to investment guidelines and the ability to manage risk commensurate with the investment style and objective for which they were hired. We continuously monitor the value of assets by class and routinely rebalance our portfolio with the goal of meeting our target allocations. The strategy for equity assets is to minimize concentrations of risk by investing primarily in companies in a diversified mix of industries worldwide, while targeting neutrality in exposure to global versus regional markets, fund types and fund managers.

The strategy for bonds emphasizes investment-grade corporate and government debt with maturities matching a portion of the longer duration pension liabilities. The bonds strategy also includes a high yield element, which is generally shorter in duration. A small portion of U.S. plan assets is allocated to private equity partnerships and real estate asset fund investments for diversification, providing opportunities for above market returns. Allowable investments under the plan agreements include equity securities, fixed income securities, mutual funds, venture capital funds, real estate and cash and equivalents. In addition, investments in futures and option contracts, commodities and other derivatives are allowed in commingled fund allocations managed by professional investment managers. Investments prohibited under the plan agreements include private placements and short selling of stock. No shares of our common stock were held by our defined benefit pension plans as of December 31, 2013 and 2012.

Actual asset allocation percentages of each class of our domestic and foreign pension plan assets as of December 31, 2013 and 2012, along with the targeted asset investment allocation percentages, each of which is based on the midpoint of an allocation range, were as follows:

Securities loaned are required to be fully collateralized by cash or other securities. The gross collateral and the related liability to return collateral amounted to $13.7 and $31.4 at December 31, 2013 and 2012, respectively, and have been included within "Level 2" of the fair value hierarchy in the tables above.

During 2013, in connection with our periodic review of the classification of assets within the fair value hierarchy, the balance of one fixed income common trust fund was transferred from Level 1 to Level 2 of the fair value hierarchy (the fair value of this fund was $16.6 and $69.2 at December 31, 2013 and 2012, respectively), and two fixed income common trust funds were transferred from Level 2 to Level 1 of the fair value hierarchy (the fair values of these funds were $27.6 and $46.3 at December 31, 2013 and 2012, respectively). There were no significant transfers between Level 1 and Level 2 of the fair value hierarchy during 2012. It is our policy to recognize transfers between Levels at the beginning of the fiscal year.

The following table summarizes changes in the fair value of Level 3 assets for the years ended December 31, 2013 and 2012:

	Global Equity Common Trust Funds			Commingled Global Fund Allocations			Fixed Income Common Trust Funds			Other			Total

During 2013, in connection with our periodic review of the classification of assets within the fair value hierarchy, the balance of one commingled global fund was transferred from Level 3 assets to Level 2 assets. There were no transfers in or out of Level 3 assets in 2012.

Employer Contributions — We currently fund U.S. pension plans in amounts equal to the minimum funding requirements of the Employee Retirement Income Security Act of 1974, plus additional amounts that may be approved from time to time. During 2013, we made contributions of $277.9 to our qualified domestic pension plans, including a $250.0 discretionary contribution, and direct benefit payments of $6.3 to our non-qualified domestic pension plans. In 2014, we expect to make minimum required funding contributions of $0.1 to our qualified domestic pension plans and direct benefit payments of $9.1 to our non-qualified domestic pension plans.

Many of our foreign plan obligations are unfunded in accordance with local laws. These plans have no assets and instead are funded by us on a pay as you go basis in the form of direct benefit payments. To our foreign plans that are funded, we made contributions of $16.6 in 2013, which included $2.3 of contributions that relate to businesses that have been classified as discontinued operations. In addition, to our foreign plans that are unfunded, we made direct benefit payments of $3.7 in 2013. In 2014, we expect to make minimum required funding contributions of $11.2, which will include $3.0 of contributions that relate to businesses that have been classified as discontinued operations, and $2.8 of direct benefit payments to our foreign pension plans.

Estimated Future Benefit Payments — Following is a summary, as of December 31, 2013, of the estimated future benefit payments for our pension plans in each of the next five fiscal years and in the aggregate for five fiscal years thereafter. Benefit payments are paid from plan assets or directly by us for our non-funded plans. The expected benefit payments are estimated based on the same assumptions used at December 31, 2013 to measure our obligations and include benefits attributable to estimated future employee service.

Estimated minimum benefit payments:
(Domestic and foreign pension plans)

	Domestic Pension Benefits		Foreign Pension Benefits

2014	$	35.9	$	14.2
2015		81.4		15.3
2016		21.0		16.2
2017		23.4		17.1
2018		25.1		17.3
Subsequent five years		170.7		92.9

Obligations and Funded Status — The funded status of our pension plans is dependent upon many factors, including returns on invested assets and the level of market interest rates. The combined unfunded status of our pension plans as of December 31, 2013 has decreased since December 31, 2012, primarily as a result of a $250.0 discretionary contribution to our qualified domestic pension plan and, to a lesser extent, higher discount rates being used to value the domestic plans in 2013 compared to 2012. Our non-funded pension plans account for $198.6 of the current underfunded status, as these plans are not required to be funded. The following tables show the domestic and foreign pension plans' funded status and amounts recognized in our consolidated balance sheets:

Assumptions — Actuarial assumptions used in accounting for our domestic and foreign pension plans were as follows:

	Year ended December 31,

	2013			2012			2011
Domestic Pension Plans
Weighted-average actuarial assumptions used in determining net periodic pension expense:
Discount rate		3.85	%		4.69	%		5.22	%
Rate of increase in compensation levels		3.75	%		3.75	%		4.00	%
Expected long-term rate of return on assets		7.25	%		7.25	%		7.25	%
Weighted-average actuarial assumptions used in determining year-end benefit obligations:
Discount rate		4.77	%		3.74	%		4.69	%
Rate of increase in compensation levels		3.75	%		3.75	%		3.75	%
Foreign Pension Plans
Weighted-average actuarial assumptions used in determining net periodic pension expense:
Discount rate		4.35	%		5.10	%		5.42	%
Rate of increase in compensation levels		3.91	%		3.92	%		4.15	%
Expected long-term rate of return on assets		6.45	%		6.56	%		7.00	%
Weighted-average actuarial assumptions used in determining year-end benefit obligations:
Discount rate		4.23	%		4.35	%		5.10	%
Rate of increase in compensation levels		3.92	%		3.91	%		3.92	%

We review the pension assumptions annually. Pension income or expense for the year is determined using assumptions as of the beginning of the year (except for the effects of recognizing changes in the fair value of plan assets and actuarial gains and losses in the fourth quarter of each year), while the funded status is determined using assumptions as of the end of the year. We determined assumptions and established them at the respective balance sheet date using the following principles: (i) the expected long-term rate of return on plan assets is established based on forward looking long-term expectations of asset returns over the expected period to fund participant benefits based on the target investment mix of our plans; (ii) the discount rate is determined by matching the expected projected benefit obligation cash flows for each of the plans to a yield curve that is representative of long-term, high-quality (rated AA or higher) fixed income debt instruments as of the measurement date; and (iii) the rate of increase in compensation levels is established based on our expectations of current and foreseeable future increases in compensation. In addition, we consider advice from independent actuaries.

Multiemployer Benefit Plans

Upon acquisition of Clyde Union, we assumed participation in a multiemployer benefit plan under the terms of a collective-bargaining agreement that covers Clyde Union's domestic union-represented employees. The risks of participating in these multiemployer plans are different from single-employer plans in the following aspects:

•

Assets contributed to the multiemployer plan by us may be used to provide benefits to employees of other participating employers;

•

If a participating employer stops contributing to the plan, the unfunded obligations of the plan may be borne by the remaining participating employers; and

•

If we choose to stop participating in the multiemployer plan, we may be required to pay an amount based on the underfunded status of the plan, referred to as a withdrawal liability.

We participate in the following multiemployer benefit plan:

Pension Fund		EIN Pension Plan Number			Pension Protection Act Zone Status — 2013		Financial Improvement Plan / Rehabilitation Plan Status Pending			2013 Contributions			2012 Contributions			Surcharge Imposed			Expiration Date of Collective Bargaining Agreement

IAM National Pension Fund, National Pension Plan			51-6031295-002		Green			No		$	0.4		$	0.3			No			August 12, 2014

The contributions made by Clyde Union during 2013 and 2012 were not more than 5% of the total contributions made to the IAM National Pension Fund, National Pension Plan ("IAM"). In 2011, the IAM began applying an election for funding relief which allows the IAM to amortize the investment losses incurred for the plan year ended December 31, 2008 over a period of up to 29 years (as opposed to 15 years that would otherwise have been required). Furthermore, in accordance with the election, the current asset valuation method has been updated to recognize the investment losses incurred during the 2008 plan year over a ten-year period as opposed to the previous period of five years.

Postretirement Benefit Plans

Employer Contributions and Future Benefit Payments — Our postretirement medical plans are unfunded and have no plan assets, but are instead funded by us on a pay as you go basis in the form of direct benefit payments or policy premium payments. In 2013, we made benefit payments of $14.7 (net of federal subsidies of $0.7) to our postretirement benefit plans. Following is a summary, as of December 31, 2013, of the estimated future benefit payments and expected federal subsidies for our postretirement plans in each of the next five fiscal years and in the aggregate for five fiscal years thereafter. The expected benefit payments and federal subsidies are estimated based on the same assumptions used at December 31, 2013 to measure our obligations and include benefits attributable to estimated future employee service.

	Postretirement Payments, net of Subsidies		Postretirement Subsidies

2014	$	14.0	$	1.4
2015		13.5		1.4
2016		12.9		1.3
2017		12.2		1.3
2018		11.6		1.3
Subsequent five years		48.4		5.4

Obligations and Funded Status — The following tables show the postretirement plans' funded status and amounts recognized in our consolidated balance sheets:

	Postretirement Benefits

	2013			2012
Change in accumulated postretirement benefit obligation:
Accumulated postretirement benefit obligation — beginning of year	$	148.7		$	148.7
Service cost		0.5			0.5
Interest cost		4.8			6.1
Actuarial (gains) losses		(7.8	)		7.2
Benefits paid		(14.7	)		(13.8	)


Accumulated postretirement benefit obligation — end of year	$	131.5		$	148.7




Funded status at year-end	$	(131.5	)	$	(148.7	)
Amounts recognized in the consolidated balance sheets consist of:
Accrued expenses	$	(13.7	)	$	(14.6	)
Other long-term liabilities		(117.8	)		(134.1	)


Net amount recognized	$	(131.5	)	$	(148.7	)




Amount recognized in accumulated other comprehensive income (pre-tax) consists of — net prior service credits	$	(0.3	)	$	(1.7	)

The net periodic postretirement benefit (income) expense included the following components:

	Year ended December 31,

	2013			2012			2011
Service cost	$	0.5		$	0.5		$	0.4
Interest cost		4.8			6.1			7.0
Amortization of unrecognized prior service credits		(1.4	)		(1.4	)		(1.4	)
Recognized net actuarial (gains) losses		(7.8	)		7.3			(3.9	)


Net periodic postretirement benefit (income) expense	$	(3.9	)	$	12.5		$	2.1

Actuarial assumptions used in accounting for our domestic postretirement plans were as follows:

	Year ended December 31,

	2013			2012			2011
Assumed health care cost trend rates:
Heath care cost trend rate for next year		6.98	%		7.13	%		7.52	%
Rate to which the cost trend rate is assumed to decline (the ultimate trend rate)		5.00	%		5.00	%		5.00	%
Year that the rate reaches the ultimate trend rate		2024			2019			2019
Discount rate used in determining net periodic postretirement benefit expense		3.37	%		4.36	%		4.85	%
Discount rate used in determining net year-end postretirement benefit obligation		4.23	%		3.37	%		4.36	%

The accumulated postretirement benefit obligation was determined using the terms and conditions of our various plans, together with relevant actuarial assumptions and health care cost trend rates. It is our policy to review the postretirement assumptions annually. The assumptions are determined by us and are established based on our prior experience and our expectations that future rates will decline. In addition, we consider advice from independent actuaries.

Assumed health care cost trend rates can have a significant effect on the amounts reported for the postretirement benefit plans. Including the effects of recognizing actuarial gains and losses into earnings, a one percentage point increase in the assumed health care cost trend rate would have increased our estimated 2013 postretirement expense by $8.1, and a one percentage point decrease in the assumed health care cost trend rate would have decreased our estimated 2013 postretirement expense by $7.3.

Defined Contribution Retirement Plans

We maintain a defined contribution retirement plan (the "DC Plan") pursuant to Section 401(k) of the U.S. Internal Revenue Code. Under the DC Plan, eligible U.S. employees may voluntarily contribute up to 50% of their compensation into the DC Plan and we match a portion of participating employees' contributions. Our matching contributions are primarily made in newly issued shares of company common stock and are issued at the prevailing market price. The matching contributions vest with the employee immediately upon the date of the match and there are no restrictions on the resale of common stock held by employees.

Under the DC Plan, we contributed 0.206, 0.266 and 0.271 shares of our common stock to employee accounts in 2013, 2012 and 2011, respectively. Compensation expense is recorded based on the market value of shares as the shares are contributed to employee accounts. We recorded $15.1 in 2013, $15.3 in 2012 and $14.8 in 2011 as compensation expense related to the matching contribution.

Certain collectively-bargained employees participate in the DC Plan with company contributions not being made in company common stock, although company common stock is offered as an investment option under these plans.

We also maintain a Supplemental Retirement Savings Plan ("SRSP"), which permits certain members of our senior management and executive groups to defer eligible compensation in excess of the amounts allowed under the DC Plan. We match a portion of participating employees' deferrals to the extent allowable under the SRSP provisions. The matching contributions vest with the participant immediately. Our funding of the participants' deferrals and our matching contributions are held in certain mutual funds (as allowed under the SRSP), as directed by the participant. The fair values of these assets, which totaled $46.2 and $45.9 at December 31, 2013 and 2012, respectively, are based on quoted prices in active markets for identical assets (Level 1). In addition, the assets under the SRSP are available to the general creditors in the event of our bankruptcy and, thus, are maintained on our consolidated balance sheets within other non-current assets, with a corresponding amount in other long-term liabilities for our obligation to the participants. Lastly, these assets are accounted for as trading securities. During 2013, 2012 and 2011, we recorded additional compensation expense of $0.3, $0.3 and $0.4, respectively, relating to our matching contributions to the SRSP.

As discussed in Note 1, we identified certain misstatements associated with previously reported income tax accounts. To correct for these misstatements, and as permitted by SAB No. 108, we have reduced retained earnings, SPX's shareholders' equity, and total equity by $53.8 as of December 31, 2010, with an offsetting increase primarily to income taxes payable. In addition, we have decreased the income tax benefit for 2012 by $1.4 and increased the income tax benefit for 2011 by $10.7, with the offset primarily to income taxes payable, in the respective accompanying consolidated financial statements. See Note 18 for the impact of these corrections on previously reported amounts for the years ended December 31, 2012 and 2011.

The reconciliation of income tax computed at the U.S. federal statutory tax rate to our effective income tax rate was as follows:

General Matters

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. We periodically assess deferred tax assets to determine if they are likely to be realized and the adequacy of deferred tax liabilities, incorporating the results of local, state, federal and foreign tax audits in our estimates and judgments.

At December 31, 2013, we had the following tax loss carryforwards available: state tax loss carryforwards of approximately $449.0 and tax losses of various foreign jurisdictions of approximately $817.0, all of which are reported in continuing operations. We also had state tax credit carryforwards of $4.1. Of these amounts, approximately $6.0 expire in 2014 and $506.0 expire at various times between 2014 and 2033. The remaining carryforwards have no expiration date.

Realization of deferred tax assets, including those associated with net operating loss and credit carryforwards, is dependent upon generating sufficient taxable income in the appropriate tax jurisdiction. We believe that it is more likely than not that we may not realize the benefit of certain of these deferred tax assets and, accordingly, have established a valuation allowance against certain of these deferred tax assets. Although realization is not assured for the remaining deferred tax assets, we believe it is more likely than not that the deferred tax assets will be realized through future taxable earnings or tax planning strategies. However, deferred tax assets could be reduced in the near term if our estimates of taxable income are significantly reduced or tax planning strategies are no longer viable. The valuation allowance increased by $21.2 in 2013 and increased by $3.6 in 2012. Of the net increase in 2013, $0.5 was recognized as a decrease in tax expense from continuing operations. Of the net increase in 2012, $5.4 was recognized as a decrease in tax expense from continuing operations.

The amount of income tax that we pay annually is dependent on various factors, including the timing of certain deductions. These deductions can vary from year to year, and, consequently, the amount of income taxes paid in future years will vary from the amounts paid in prior years.

Undistributed Foreign Earnings

In general, it is our practice and intention to reinvest the earnings of our non-U.S. subsidiaries in those operations. As of December 31, 2013, we had not recorded a provision for U.S. or foreign withholding taxes on approximately $1,634.0 of the excess of the amount for financial reporting over the tax basis of investments in foreign subsidiaries that are essentially permanent in duration. Generally, such amounts become subject to U.S. taxation upon the remittance of dividends and under certain other circumstances. It is not practicable to estimate the amount of a deferred tax liability related to the undistributed earnings of these foreign subsidiaries, in the event that these earnings are no longer considered to be indefinitely reinvested, due to the hypothetical nature of the calculation.

There are discrete amounts of foreign earnings (approximately $318.0), primarily related to the gain on sale of our Service Solutions business, where we do plan to repatriate the earnings in the future. During 2012, we provided $100.8 of U.S. and foreign withholding taxes on such earnings, with $91.8 of such amount recorded to discontinued operations.

Unrecognized Tax Benefits

As of December 31, 2013, we had gross unrecognized tax benefits of $128.4 (net unrecognized tax benefits of $72.9), of which $72.3, if recognized, would impact our effective tax rate from continuing operations. Similarly, at December 31, 2012 and 2011, we had gross unrecognized tax benefits of $108.4 (net unrecognized tax benefits of $72.5) and $120.4 (net unrecognized tax benefits of $103.2), respectively.

We classify interest and penalties related to unrecognized tax benefits as a component of our income tax provision. As of December 31, 2013, gross accrued interest excluded from the amounts above totaled $12.4 (net accrued interest of $8.6), while the related amounts as of December 31, 2012 and 2011 were $12.8 (net accrued interest of $8.6) and $16.6 (net accrued interest of $12.4), respectively. Our income tax (provision) benefit for the years ended December 31, 2013, 2012 and 2011 included gross interest income of $0.2, $2.9 and $1.2, respectively, resulting from a reduction in our liability for uncertain tax positions. As of December 31, 2013, penalties excluded from the amounts above totaled $7.1, while the related amounts as of December 31, 2012 and 2011 were $7.1 and $5.6, respectively. Our income tax benefit for the years ended December 31, 2012 and 2011 included penalties of $1.5 and $0.6, respectively, while there were no penalties included in the income tax provision for the year ended December 31, 2013.

Based on the outcome of certain examinations or as a result of the expiration of statutes 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 $65.0 to $75.0. The previously unrecognized tax benefits relate to a variety of tax issues including an estimate of the previously unrecorded tax liability referenced in Note 1, tax matters relating to prior acquisitions and dispositions, transfer pricing, and various state matters.

The aggregate changes in the balance of unrecognized tax benefits for the years ended December 31, 2013, 2012 and 2011 were as follows:

	Year ended December 31,

	2013			2012			2011
Unrecognized tax benefit — opening balance	$	108.4		$	120.4		$	142.7
Gross increases — tax positions in prior period		0.5			20.6			3.3
Gross decreases — tax positions in prior period		(2.3	)		(33.9	)		(23.4	)

Settlements		(1.1	)		(7.1	)		(0.9	)
Lapse of statute of limitations		(5.5	)		(2.7	)		(11.5	)
Change due to foreign currency exchange rates		—			(0.1	)		(0.7	)


Unrecognized tax benefit — ending balance	$	128.4		$	108.4		$	120.4

Other Tax Matters

During 2013, our income tax provision was impacted by the following income tax benefits: (i) $9.5 related to net reductions in valuation allowances recorded against certain foreign deferred income tax assets; (ii) $6.5 related to various audit settlements and statute expirations; and (iii) $4.1 associated with the Research and Experimentation Credit generated in 2012.

During 2012, our income tax benefit was impacted by: (i) an income tax benefit of $26.3 associated with the $281.4 impairment charge recorded for our Cooling reporting unit, as the majority of the goodwill for the Cooling reporting unit has no basis for income tax purposes; (ii) taxes provided of $15.4 on foreign dividends and undistributed earnings that were no longer considered to be indefinitely reinvested; (iii) incremental tax expense of $6.1 associated with the deconsolidation of our dry cooling business in China, as the goodwill allocated to the transaction was not deductible for income tax purposes; and (iv) valuation allowances that were recorded against deferred income tax assets during the year of $5.4. The unfavorable impact of these items was offset partially by income tax benefits of $22.3 associated with audit closures, settlements, statute expirations, and other changes in the accrual for uncertain tax positions, with the most notable being the closure of our German tax examination for the years 2005 through 2009.

During 2011, we adopted an alternative method of allocating certain expenses between foreign and domestic sources for federal income tax purposes. As a result of this method change, we determined that it was more likely than not that we would be able to utilize our then-existing foreign tax credits within the remaining carryforward period. Accordingly, we released the valuation allowance on our foreign tax credit carryforwards in 2011, resulting in an income tax benefit of $38.5. In addition, the effective tax rate for the year ended December 31, 2011 was impacted favorably by tax benefits of $2.5 associated with the conclusion of a Canadian appeals process and $7.7 of tax credits related to the expansion of our power transformer facility in Waukesha, WI. These tax benefits were offset partially 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.

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 consolidated balance sheets based on the expectation as to the timing of when the matters will be resolved. As events change and resolutions occur, these accruals are adjusted, such as in the case of audit settlements with taxing authorities.

Our federal income tax returns for the 2007 to 2012 tax years are subject to examination. The IRS is currently auditing the 2007 to 2011 tax return years. With regard to all open tax years, 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 of the respective tax return. 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. The most significant of these are in Denmark for the 2006 to 2010 tax years and South Africa for the 2005 to 2010 tax years. 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 reached the final stages of the appeals process for any of 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.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Senior Credit Facilities

On December 23, 2013, we amended our senior credit facilities to provide for committed senior secured financing in an aggregate amount of $2,075.0, consisting of the following (each with a final maturity of December 23, 2018):

•

A term loan facility of $575.0, of which $475.0 was outstanding at December 31, 2013 and under which an additional $100.0 is available for borrowings on a delayed draw basis through June 20, 2014;

•

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, GBP and other currencies, in an aggregate principal amount up to the equivalent of $200.0;

•

A participation foreign credit instrument facility, available for performance letters of credit and guarantees, in an aggregate principal amount up to the equivalent of $800.0; and

•

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

The term loan of $475.0 is repayable in quarterly installments (with annual aggregate repayments, as a percentage of the initial principal amount of $475.0, together with any additional borrowings of up to $100.0 available to be drawn under the facility on a delayed draw basis through June 20, 2014, of 5.0%, beginning with the first fiscal quarter of 2015), with the remaining balance repayable in full on December 23, 2018.

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 cash 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 defined in the credit agreement generally as the ratio of consolidated total debt (excluding the face amount of undrawn letters of credit, bank undertakings or analogous instruments and net of cash and cash equivalents in excess of $50.0) as of the last day of any fiscal quarter to consolidated adjusted EBITDA for the four quarters ended on such date) 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).

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 December 23, 2013 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 December 31, 2013, we had $445.5 of available borrowing capacity under our revolving credit facilities after giving effect to $54.5 reserved for outstanding letters of credit. In addition, at December 31, 2013, we had $328.4 of available issuance capacity under our foreign credit instrument facilities after giving effect to $671.6 reserved for outstanding letters of credit.

We also may seek additional commitments, without the consent from the existing lenders, to add an incremental term loan facility and/or increase the commitments in respect of the domestic revolving credit facility, the global revolving credit facility, the participation foreign credit instrument facility and/or the bilateral foreign credit instrument facility by up to an aggregate principal amount not to exceed (x) $1,000.0 or (y) such greater amount that would not cause our Consolidated Senior Secured Leverage Ratio to exceed 2.75 to 1.00.

We are the borrower under all the facilities, and certain of our foreign subsidiaries are borrowers under the foreign credit instrument facilities (and we may in the future designate other subsidiaries to be borrowers under the revolving credit facilities and the foreign credit instrument facilities).

All borrowings and other extensions of credit under our senior credit facilities are subject to the satisfaction of customary conditions, including absence of defaults and accuracy in material respects of representations and warranties.

The letters of credit under the domestic revolving credit facility are stand-by letters of credit requested by any borrower on behalf of itself or any of its subsidiaries or certain joint ventures. The foreign credit instrument facility is used to issue credit instruments, including bank undertakings to support primarily commercial contract performance.

The interest rates applicable to loans under our senior credit facilities are, at our option, equal to either (i) an alternate base rate (the higher of (a) the federal funds effective rate plus 0.5%, (b) the prime rate of Bank of America, N.A., and (c) the one-month LIBOR plus 1.0%) or (ii) a reserve-adjusted LIBOR (as defined in the senior credit facilities) for dollars (Eurodollars) plus, in each case, an applicable margin percentage, which varies based on our Consolidated Leverage Ratio. We may elect interest periods of one, two, three or six months for Eurodollar borrowings. The per annum fees charged and the interest rate margins applicable to Eurodollar and alternate base rate loans are as follows:

Consolidated Leverage Ratio

Greater than or equal to 3.00 to 1.00	0.35	%	0.35	%	2.00	%	0.35	%	1.25	%	2.00	%	1.00	%
Between 2.00 to 1.00 and 3.00 to 1.00	0.30	%	0.30	%	1.75	%	0.30	%	1.00	%	1.75	%	0.75	%
Between 1.50 to 1.00 and 2.00 to 1.00	0.275	%	0.275	%	1.50	%	0.275	%	0.875	%	1.50	%	0.50	%
Between 1.00 to 1.00 and 1.50 to 1.00	0.25	%	0.25	%	1.375	%	0.25	%	0.80	%	1.375	%	0.375	%
Less than 1.00 to 1.00	0.225	%	0.225	%	1.25	%	0.225	%	0.75	%	1.25	%	0.25	%

The weighted-average interest rate of our outstanding borrowings under our senior credit facilities was approximately 1.92% at December 31, 2013.

Bilateral foreign credit fees and commitments are as specified above, unless otherwise agreed with the bilateral foreign issuing lender. We also pay fronting fees on the outstanding amounts of letters of credit and foreign credit instruments (in the participation facility) at the rates of 0.125% per annum and 0.25% per annum, respectively.

Our senior credit facilities require mandatory prepayments in amounts equal to the net proceeds from the sale or other disposition of, including from any casualty to, or governmental taking of, property in excess of specified values (other than in the ordinary course of business and subject to other exceptions). Mandatory prepayments will be applied to repay, first, any amounts outstanding under the term loans and any other incremental term loans that we may have outstanding in the future, in the manner and order selected by us, and second, after the term loans and any such incremental term loans have been repaid in full, amounts (or cash collateralize letters of credit) outstanding under the global revolving credit facility and the domestic revolving credit facility (without reducing the commitments thereunder). No prepayment is required generally to the extent the net proceeds are reinvested in permitted acquisitions, permitted investments or assets to be used in our business within 360 days of the receipt of such proceeds. In addition, no prepayment is required for the net proceeds from the sale of our joint venture interest in EGS or for the net proceeds of certain other potential divestitures specifically identified in the agreement governing the senior credit facilities.

We may voluntarily prepay loans under our senior credit facilities, in whole or in part, without premium or penalty. Any voluntary prepayment of loans will be subject to reimbursement of the lenders' breakage costs in the case of a prepayment of Eurodollar rate borrowings other than on the last day of the relevant interest period.

Indebtedness under our senior credit facilities is guaranteed by:

•

Each existing and subsequently acquired or organized domestic material subsidiary, with specified exceptions; and

•

SPX Corporation with respect to the obligations of our foreign borrower subsidiaries under the global revolving credit facility, the participation foreign credit instrument facility and the bilateral participation foreign credit instrument facility.

Indebtedness under our senior credit facilities is secured by a first priority pledge and security interest in 100% of the capital stock of our domestic subsidiaries (with certain exceptions) held by us or our domestic subsidiary guarantors and 65% of the capital stock of our material first-tier foreign subsidiaries (with certain exceptions). If our corporate credit rating is less than "Ba2" (or not rated) by Moody's and less than "BB" (or not rated) by S&P, then we and our domestic subsidiary guarantors are required to grant security interests, mortgages and other liens on substantially all of our assets. If our corporate credit rating is "Baa3" or better by Moody's or "BBB-" or better by S&P and no defaults would exist, then all collateral security will be released and the indebtedness under our senior credit facilities will be unsecured.

At December 31, 2013, 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.

Senior Notes

In August 2010, we issued, in a private placement, $600.0 aggregate principal amount of 6.875% senior unsecured notes that mature in August 2017. We used the proceeds from the offering to repay the remaining balance under the term loan of our then-existing senior credit facilities of $562.5, to pay $26.9 of termination costs (including $2.6 of accrued interest) for Swaps related to the then-existing term loan, and the remainder to pay the majority of the financing costs incurred in connection with the offering. The interest payment dates for these notes are March 1 and September 1 of each year. The notes are redeemable, in whole or in part, at any time prior to maturity at a price equal to 100% of the principal amount thereof plus an applicable premium, plus accrued and unpaid interest. If we experience certain types of change of control transactions, we must offer to repurchase the notes at 101% of the aggregate principal amount of the notes repurchased, plus accrued and unpaid interest. These notes are unsecured and rank equally with all our existing and future unsubordinated unsecured senior indebtedness, but are effectively junior to our senior credit facilities. The indenture governing these notes contains covenants that, among other things, limit our ability to incur liens, enter into sale and leaseback transactions and consummate some mergers. During the third quarter of 2011, these senior notes became freely tradable. Payment of the principal, premium, if any, and interest on these notes is guaranteed on a senior unsecured basis by our domestic subsidiaries. The likelihood of having to make payments under the guarantee is considered remote.

In December 2007, we issued, in a private placement, $500.0 aggregate principal amount of 7.625% senior unsecured notes that mature in December 2014. We used the net proceeds from the offering for general corporate purposes, including the financing of our acquisition of APV. The interest payment dates for these notes were June 15 and December 15 of each year. The notes are redeemable, in whole, or in part, at any time prior to maturity at a price equal to 100% of the principal amount thereof plus a premium, plus accrued and unpaid interest. If we experience certain types of change of control transactions, we must offer to repurchase the notes at 101% of the aggregate principal amount of the notes repurchased, plus accrued and unpaid interest. These notes are unsecured and rank equally with all our existing and future unsecured senior indebtedness, but are effectively junior to our senior credit facilities. The indenture governing these notes contains covenants that, among other things, limit our ability to incur liens, enter into sale and leaseback transactions and consummate some mergers. During the first quarter of 2009, these senior notes became freely tradable. On February 11, 2014, we completed the redemption of all of the 7.625% senior notes for a total redemption price of $530.6, plus approximately $2.0 in transaction costs. As a result of the redemption, we will record a charge in our first quarter 2014 operating results equal to the premium paid plus transaction costs incurred to redeem the notes.

At December 31, 2013, we were in compliance with all covenant provisions of our senior notes.

Other Borrowings and Financing Activities

Certain of our businesses purchase goods and services under purchase card programs allowing for payment beyond their normal payment terms. As of December 31, 2013 and 2012, the participating businesses had $25.4 and $27.9, respectively, outstanding under these arrangements. As these arrangements extend the payment of our businesses' payables beyond their normal payment terms through third-party lending institutions, we have classified these amounts as short-term debt.

We are party to a trade receivables financing agreement, whereby we can borrow, on a continuous basis, up to $80.0. Availability of funds may fluctuate over time given changes in eligible receivable balances, but will not exceed the $80.0 program limit. The facility contains representations, warranties, covenants and indemnities customary for facilities of this type. The facility does not contain any covenants that we view as materially constraining to the activities of our business.

We had $5.3 of letters of credit outstanding under separate arrangements in China and India.

- 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.

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, South African Rand, CNY and GBP.

From time to time, we enter into 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"), because 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. 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 AOCI. These changes in fair value are 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 is recorded as a component of "Other income (expense), net" in the period in which it occurs. To the extent 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 in which it occurs.

We had FX forward contracts with an aggregate notional amount of $191.3 and $107.3 outstanding as of December 31, 2013 and 2012, respectively, with all such contracts scheduled to mature in 2014. We also had FX embedded derivatives with an aggregate notional amount of $145.8 and $96.3 at December 31, 2013 and 2012, respectively, with scheduled maturities of $88.7, $44.8, $11.0 and $1.3 in 2014, 2015, 2016 and years thereafter, respectively. The unrealized losses, net of taxes, recorded in AOCI related to FX forward contracts were $1.0 and $3.4 as of December 31, 2013 and 2012, respectively. We anticipate reclassifying the unrealized loss as of December 31, 2013 to income over the next 12 months. The net gain (loss) recorded in "Other income (expense), net" related to FX forward contracts and embedded derivatives totaled $0.5 in 2013, $(0.2) in 2012 and $(37.0) in 2011.

Beginning on August 30, 2011, we entered into FX forward contracts to hedge a significant portion of the Clyde Union acquisition purchase price, which, as previously noted, was paid in GBP. From the inception of these contracts until December 22, 2011 (the date on which the contracts were settled), the U.S. dollar strengthened against the GBP by approximately 4%. As a result, we recorded charges and made cash payments to settle the contracts during 2011 of $34.6, with the charges recorded to "Other income (expense), net."

Commodity Contracts

From time to time, we enter into commodity contracts to manage the exposure on forecasted purchases of commodity raw materials. At December 31, 2013 and 2012, the outstanding notional amount of commodity contracts was 3.4 and 3.3 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 AOCI associated with our commodity contracts to cost of products sold when the forecasted transaction impacts earnings. As of December 31, 2013 and 2012, the fair value of these contracts was $0.4 (current asset) and $0.2 (current asset), respectively. The unrealized gain, net of taxes, recorded in AOCI was $0.2 and $0.1 as of December 31, 2013 and 2012, respectively. We anticipate reclassifying the unrealized gain as of December 31, 2013 to income over the next 12 months.

The following summarizes the gross and net fair values of our FX forward and commodity contracts by counterparty at December 31, 2013 and 2012, respectively:

Concentrations of Credit Risk

Financial instruments that potentially subject us to significant concentrations of credit risk consist of cash and equivalents, trade accounts receivable, and foreign currency forward and commodity contracts. These financial instruments, other than trade accounts receivable, are placed with high-quality financial institutions throughout the world. We periodically evaluate the credit standing of these financial institutions.

We have credit loss exposure in the event of nonperformance by counterparties to the above financial instruments, but have no other off-balance-sheet credit risk of accounting loss. We anticipate, however, that counterparties will be able to fully satisfy their obligations under the contracts. We do not obtain collateral or other security to support financial instruments subject to credit risk, but we do monitor the credit standing of counterparties.

Concentrations of credit risk arising from trade accounts receivable are due to selling to customers in a particular industry. We mitigate our credit risks by performing ongoing credit evaluations of our customers' financial conditions and obtaining collateral, advance payments, or other security when appropriate. No one customer, or group of customers that to our knowledge are under common control, accounted for more than 10% of our revenues for any period presented.

- Definition

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. Also, 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, which are determined in accordance with the Contingencies Topic of the Codification, totaled $610.1 (including $565.0 for risk management matters) and $548.6 (including $501.3 for risk management matters) at December 31, 2013 and 2012, respectively. Of these amounts, $561.8 and $497.0 are included in "Other long-term liabilities" within our consolidated balance sheets at December 31, 2013 and 2012, 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 $496.7 and $430.6 at December 31, 2013 and 2012, respectively, included in "Other assets" within our 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 the aggregate, on our business, financial condition, results of operations or cash flows. At December 31, 2013, we had liabilities for site investigation and/or remediation at 94 sites (95 sites at December 31, 2012) 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 generally do not discount our environmental accruals and do not reduce them by anticipated insurance recoveries. 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.

In the case of contamination at offsite, third-party disposal sites, as of December 31, 2013, we had been notified that we are potentially responsible and have received other notices of potential liability pursuant to various environmental laws at 23 sites (23 sites at December 31, 2012) at which the liability has not been settled, of which 6 sites (6 sites at December 31, 2012) 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 our aggregate liability, if any, related to these sites is not material to our consolidated financial statements. 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 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 statements of operations.

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 consolidated financial statements, we account for our share of the revenues and profits under the consortium arrangements. As of December 31, 2013, our share of the aggregate contract value on open consortium arrangements was $139.3 (of which approximately 87% had been recognized as revenue), and the aggregate contract value on open consortium arrangements was $433.8. As of December 31, 2012, our share of the aggregate contract value on open consortium arrangements was $264.4 (of which approximately 62% had been recognized as revenue), and the aggregate contract value on open consortium arrangements was $740.9. At December 31, 2013 and 2012, we recorded liabilities of $1.7 and $1.5, respectively, representing the estimated fair value of our potential obligation under the joint and several liability provisions associated with the consortium arrangements.

Executive Agreements

The Board of Directors has approved employment agreements for six of our executives. These agreements have rolling terms of either one year or two years and specify the executive's current compensation, benefits and perquisites, the executive's entitlements upon termination of employment or a change in control, and other employment rights and responsibilities. In addition, one executive officer has an outstanding non-interest bearing 20-year relocation home loan totaling $1.5 granted in connection with the 2001 move of our corporate headquarters. In the event of the death or permanent disability of the employee or a change in control of SPX, we will forgive the note and pay the employee or his estate an amount equal to the employee's tax liability as a result of the loan forgiveness.

All stock options were included in the computation of diluted income per share for the year ended December 31, 2013. The total number of stock options 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 and 0.117 for the years ended December 31, 2012 and 2011, respectively. The total number of unvested restricted stock shares and restricted stock units that were not included in the computation of diluted income per share because required market thresholds for vesting (as discussed below) were not met was 0.647, 1.031, and 0.633 at December 31, 2013, 2012 and 2011, respectively.

Common Stock and Treasury Stock

At December 31, 2013, we had 200.0 authorized shares of common stock (par value $10.00). Common shares issued, treasury shares and shares outstanding are summarized in the table below.

Stock-Based Compensation

Under the 2002 Stock Compensation Plan, as amended in 2006, 2011 and 2012, up to 2.684 shares of our common stock were available for grant at December 31, 2013. 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 shares. Each share of restricted stock and restricted stock unit granted reduces availability by two shares.

During the years ended December 31, 2013, 2012 and 2011, we classified excess tax benefits from stock-based compensation of $6.3, $3.8 and $6.6, respectively, as financing cash flows and included such amounts in "Minimum withholdings paid on behalf of employees for net share settlements, net of proceeds from the exercise of employee stock options and other" within our consolidated statements of cash flows.

Restricted stock shares 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 a period of time, generally one or three years. In some instances, such as death, disability, or retirement, stock may vest concurrently with or following an employee's termination. A substantial portion of the restricted stock shares and restricted stock unit awards vest based on performance thresholds, while the remaining portion vest based on the passage of time since grant date.

Eligible employees received a target performance award in 2013 in which the employee can earn between 25% and 125% of the target award in the event the award meets the required vesting criteria. Vesting for the 2013 target performance awards is based on SPX shareholder return versus the S&P Composite 1500 Industrials Index over the three-year period ending December 31, 2015.

Each eligible non-officer employee also received an award in both 2013 and 2012 that vests ratably over three years, subject only to the passage of time. Officers received awards in 2013 that vest ratably over three years, subject to an internal performance metric.

Vesting for the 2012 and 2011 performance awards is based on the SPX shareholder return versus the S&P 500 Index. On each vesting date, we compare the SPX shareholder return to the performance of the S&P 500 Index for the prior year and for the cumulative period since the date of the grant. If SPX outperforms the S&P 500 Index for the prior year, the one-third portion of the grant associated with that year will vest. If SPX outperforms the S&P 500 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.

We grant restricted stock shares 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 0.018 shares of our common stock were available for grant at December 31, 2013. The 2013 restricted stock grants to the non-employee directors generally vest over a one-year vesting period.

The 2012 and 2011 restricted stock grants to the non-employee directors have a three-year vesting period based on SPX shareholder return versus the S&P 500 Index, and are subject to the same company performance thresholds as the employee 2012 and 2011 awards described above.

Restricted stock shares and restricted stock units that do not vest within the applicable vesting period are 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 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, and there were no options outstanding as of December 31, 2013.

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. There was no stock option expense for the years ended December 31, 2013, 2012 and 2011. Compensation expense within income from continuing operations related to restricted stock shares and restricted stock units totaled $32.8, $38.8 and $38.6 for the years ended December 31, 2013, 2012 and 2011, respectively, with the related tax benefit being $12.1, $14.8 and $14.5 for the years ended December 31, 2013, 2012 and 2011, respectively.

We use the Monte Carlo simulation model valuation technique to determine fair value of our restricted stock shares and restricted stock units as they 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 share and restricted stock unit award. We used the following assumptions in determining the fair value of the awards granted on the dates indicated below:



April 1, 2013:
SPX Corporation	35.5	%	1.29	%	0.33	%	0.7668
S&P Composite 1500 Industrials Index	21.2	%	n/a		0.33	%
January 2, 2013:
SPX Corporation	36.3	%	1.42	%	0.37	%	0.7778
S&P Composite 1500 Industrials Index	22.4	%	n/a		0.37	%
January 3, 2012:
SPX Corporation	44.3	%	1.60	%	0.44	%	0.7365
S&P 500 Index	23.1	%	n/a		0.44	%

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.

Restricted Stock Share and Restricted Stock Unit Awards

The following table summarizes the restricted stock share and restricted stock unit activity from December 31, 2010 through December 31, 2013:

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 2012, we repurchased 3.606 shares of our common stock for $245.6. During January 2013, we repurchased 1.514 shares of our common stock for $104.4, which completed the repurchases authorized under this trading plan. In addition, we repurchased 1.864 shares of our common stock on the open market for $144.6 during the year ended December 31, 2013. Lastly, on December 18, 2013, we entered into a written trading plan under Rule 10b5-1 to facilitate the repurchase of up to $500.0 of shares of our common stock on or before December 31, 2014, in accordance with a share repurchase program authorized by our Board of Directors. During December 2013, we repurchased 0.115 shares of our common stock for $11.2 under this trading plan.

During the years ended December 31, 2013, 2012 and 2011, "Common stock in treasury" was decreased by the settlement of restricted stock units issued from treasury stock of $14.2, $6.1 and $12.8, respectively, and increased by $11.0, $1.8 and $7.0, respectively, for common stock that was surrendered by recipients of restricted stock as a means of funding the related minimum income tax withholding requirements.

Preferred Stock

None of our 3.0 shares of authorized no par value preferred stock was outstanding at December 31, 2013, 2012 or 2011.

Fair Value

Fair Value

(16) 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 periods presented to the valuation techniques we use to measure asset and liability fair values on a recurring basis. Except as previously discussed in Note 10, there were no transfers between the three levels of the fair value hierarchy for the periods presented.

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, valued using valuation models based on observable market inputs such as forward rates, interest rates, our own credit risk and the credit risk of our counterparties, which comprise investment-grade financial institutions. 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 December 31, 2013, 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 had been no significant impact to the fair value of our derivative assets based on our evaluation of our counterparties' credit risks.

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 $3.0 and $3.6 at December 31, 2013 and 2012, respectively.

Certain of our investments in equity securities that are not readily marketable are accounted for under the fair value option and are classified as Level 3 assets in the fair value hierarchy, 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 December 31, 2013 and 2012, these assets had a fair value of $1.4 and $7.5, 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 December 31, 2013:

	Fair Value Measurements Using

Other current assets — FX embedded derivatives, FX forward contracts and commodity contracts	$	—	$	2.0	$	—
Other assets — Investments in equity securities		3.0		—		1.4
Accrued expenses — FX forward contracts and FX embedded derivatives		—		6.8		—
Other long-term liabilities — FX embedded derivatives		—		2.1		—

Assets and liabilities measured at fair value on a recurring basis include the following as of December 31, 2012:

During 2013, we recorded impairment charges of $6.7 related to the trademarks of certain businesses within our Flow Technology reportable segment as we determined that the fair values of the trademarks were less than the carrying values. The fair values of the trademarks were determined by applying estimated royalty rates to projected revenues, with the resulting cash flows discounted at a rate of return that reflected current market conditions (unobservable inputs — Level 3).

During 2012, we determined that the fair value of our Cooling reporting unit was less than the carrying value of its net assets (see Note 8). The fair value of our Cooling reporting unit was based upon weighting the income and market approaches, utilizing estimated cash flows and a terminal value discounted at a rate of return that reflects the relative risk of the cash flows, as well as valuation multiples derived from comparable publically-traded companies that were applied to the historical and projected operating results of the Cooling reporting unit (unobservable inputs — Level 3). We then allocated the fair value to the assets and liabilities of Cooling, which resulted in an implied value for the reporting unit's goodwill. Based on such implied value, we recorded an impairment charge related to Cooling's goodwill of $270.4. In addition, we recorded an impairment charge related to other long-term assets at Cooling of $11.0. Lastly, we recorded impairment charges of $4.5 related to trademarks for two other businesses within our Thermal Equipment and Services reportable segment. The fair values of the trademarks were determined by applying estimated royalty rates to projected revenues, with the resulting cash flows discounted at a rate of return that reflected current market conditions (unobservable inputs — Level 3).

During 2011, we determined that the fair value of our SPX Heat Transfer reporting unit was less than the carrying value of its net assets (see Note 8). The fair value of SPX Heat Transfer was based upon weighting the income and market approaches (unobservable inputs — Level 3). We then allocated the fair value to the assets and liabilities of SPX Heat Transfer, which resulted in an implied value for the reporting unit's goodwill. Based on such implied value, we recorded an impairment charge related to SPX Heat Transfer's goodwill of $20.8. In addition, we recorded an impairment charge of $7.5 related to the trademarks of SPX Heat Transfer, with the fair value of these intangibles determined by applying estimated royalty rates to projected revenues, with the resulting cash flows discounted at a rate of return that reflected current market conditions (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 December 31, 2013 and 2012 were as follows:

	December 31, 2013				December 31, 2012

	Carrying Amount		Fair Value		Carrying Amount		Fair Value
Senior notes	$	1,100.0	$	1,214.3	$	1,100.0	$	1,217.8
Term loan		475.0		475.0		475.0		475.0
Other indebtedness		27.6		27.6		34.7		34.7

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 loan 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 other indebtedness 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 December 31, 2013, with the exception of the impairment charges previously noted, we did not have any significant non-financial assets or liabilities that are required to be measured at fair value on a recurring or non-recurring basis.

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

Note: The sum of the quarters' income per share may not equal the full year per share amounts.

⁽¹⁾

During the fourth quarters of 2013 and 2012, we recognized gains (losses) of $0.8 and $(149.9), respectively, related to changes in the fair value of plan assets and actuarial gains (losses) associated with our pension and postretirement benefit plans. The income tax (provision) benefit associated with these gains (losses) was $(1.7) and $52.9, respectively.

As discussed in Note 1 to our consolidated financial statements, during December 2013 we identified certain misstatements to previously reported income tax amounts. To correct for these misstatements, we have increased "Income from continuing operations" during each of the first three quarters of 2012 by $0.1 and increased "Loss from continuing operations" for the fourth quarter of 2012 by $1.7. There are no corrections required to the results for the first three quarters of 2013.

During the fourth quarter of 2012, we recorded impairment charges of $281.4 related to the goodwill ($270.4) and other long-term assets ($11.0) of our Cooling reporting unit. The income tax benefit associated with these impairment charges was $26.3, as the majority of the goodwill for the Cooling reporting unit has no basis for income tax purposes.

⁽²⁾

During the fourth quarter of 2012, we sold our Service Solutions business to Robert Bosch GmbH resulting in a net gain of $313.4.

⁽³⁾

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 were March 30, June 29 and September 28, compared to the respective March 31, June 30 and September 29, 2012 dates. This practice only affects the quarterly reporting periods and not the annual reporting period. We had two fewer days in the first quarter of 2013 and one more day in the fourth quarter of 2013 than in the respective 2012 periods.

⁽⁴⁾

As described in Note 1 to our consolidated financial statements, we have retrospectively applied new accounting methods for recognizing changes in the fair value of plan assets and actuarial gains and losses associated with our pension and postretirement benefit plans. The impact of these changes on previously reported quarterly results and the results for the fourth quarter of 2013 is summarized below:

	First				Second				Third				Fourth

	2013*		2012*		2013*		2012*		2013*		2012*		2013**		2012*

^*: Represents an increase (decrease) from previously reported amounts.
^**: Represents an increase from amounts that would have been reported under our historical methods for recording pension and postretirement expense. Under our historical methods, we would have recorded pension/postretirement expense of $407.0 during the fourth quarter of 2013, which would have included a charge of $399.4 associated primarily with the November 2013 transfer of the pension obligations of the retirees under the Plan to Mass Mutual (see Notes 1 and 10 for additional details). Under our new methods of recording pension and postretirement expense, we recorded pension income of $5.0 during the fourth quarter of 2013. The difference between these methods on the fourth quarter 2013 results is further summarized below:

	Pre-Tax			Tax Effect			Net

(19) Effect of Accounting Changes

As described in Note 1, we have retrospectively applied the new accounting methods for recognizing changes in the fair value of plan assets and actuarial gains and losses associated with our pension and postretirement benefit plans. Accordingly, we recorded a cumulative reduction in retained earnings as of January 1, 2011 of $416.2, with a corresponding offset to AOCI. The impact of these changes on the accompanying consolidated financial statements is summarized below:

(1): "As Revised and Restated" for 2012 and 2011 represents amounts as previously reported in our 2012 Annual Report on Form 10-K (as amended), revised and restated to reflect (i) the reclassification of certain prior period amounts, including the results of discontinued operations (see Note 4), as well as (ii) the correction of prior period misstatements within our income tax accounts (see Notes 1, 11 and 18 for further information).
(2): Reflects amounts we would have reported had we not changed our accounting methods for recognizing changes in the fair value of plan assets and actuarial gains and losses.
(3): Reflects amounts reported in the accompanying consolidated financial statements as of and for the years ended December 31, 2013, 2012 and 2011.
(4): Under our historical methods of accounting for our pension and postretirement benefit plans, our pension and postretirement benefit expense for 2013 would have been a pre-tax charge of $425.6 as compared to pension and postretirement benefit income of $17.7 recognized under our new methods. The pre-tax charge under our historical methods reflects the effects of a $399.4 charge that would have been recognized as a result of the settlement of approximately 61% of the Plan's projected benefit obligation as of November 12, 2013, due primarily to the transfer of the retiree pension obligations of the Plan to Mass Mutual, as previously described.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
Summary of Significant Accounting Policies (Policies)	Dec. 31, 2013
Summary of Significant Accounting Policies
Basis of Presentation	Basis of Presentation — The consolidated financial statements include SPX Corporation's ("SPX," "our" or "we") accounts prepared in conformity with accounting principles generally accepted in the United States ("GAAP") after the elimination of intercompany transactions. Investments in unconsolidated companies where we exercise significant influence but do not have control are accounted for 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 of the entity 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. Unless otherwise indicated, amounts provided in these Notes pertain to continuing operations only (see Note 4 for information on discontinued operations).
Restatement of Previously Reported Financial Information	Restatement of Previously Reported Financial Information — Primarily during 2007 and 2008, in connection with a reorganization of certain foreign subsidiaries, an SPX foreign subsidiary (a deemed branch of SPX for U.S. income tax purposes) assumed a loan that was guaranteed by various foreign subsidiaries of SPX. In December 2013, we identified these loans and determined that they represented a deemed distribution (i.e., additional taxable income) subject to U.S. income taxes under Internal Revenue Code Section 956. In addition, we concluded that the previously unrecorded income tax liabilities associated with these intercompany loans represented misstatements in our consolidated financial statements for the years ended December 31, 2012, 2011, 2010, 2009, 2008, and 2007. Specifically, we determined that income tax expense for these years was overstated (understated) by $(1.4), $10.7, $(4.9), $(6.1), $(18.0), and $(24.8), respectively. We have evaluated the effects of these misstatements on the consolidated financial statements for each of these years in accordance with the guidance provided by SEC Staff Accounting Bulletin No. 108, codified as SAB Topic 1.N, "Considering the Effects of Prior Year Misstatements When Quantifying Misstatements in the Current Year Financial Statements," and concluded that none of these years are materially misstated. To correct these misstatements, and as permitted by SAB No. 108, we have reduced retained earnings, SPX's shareholders' equity, and total equity by $53.8 as of December 31, 2010, with an offsetting increase primarily to income taxes payable. In addition, we have decreased the income tax benefit for 2012 by $1.4 and increased the income tax benefit for 2011 by $10.7, with the offset primarily to income taxes payable, in the respective accompanying consolidated financial statements. See Note 18 for the impact of these corrections on previously reported amounts for the years ended December 31, 2012 and 2011. There are no corrections required to the results for the first three quarters of 2013.
Pension and Postretirement	Pension and Postretirement — In the fourth quarter of 2013, we elected to change our accounting methods for recognizing expense associated with all of our pension and postretirement benefit plans. Historically, actuarial gains and losses in excess of 10% of the greater of the market-related value of plan assets or the plans' projected benefit obligations (the "corridor") were recognized as a component of accumulated other comprehensive income ("AOCI") within our consolidated balance sheet and, depending on the benefit plan, we amortized these gains and losses to earnings either over the remaining average service period for the active participants or the average remaining life expectancy of the inactive participants. Additionally, for our domestic qualified pension plan, we used a calculated value of plan assets reflecting changes in the fair value of plan assets over a five-year period and we applied a fair value method for our foreign pension plans. Under our new accounting methods, we recognize changes in the fair value of plan assets and actuarial gains and losses in earnings during the fourth quarter of each year as a component of net periodic benefit expense (and we no longer apply a corridor and, therefore, no longer defer any gains or losses). These new accounting methods result in changes in the fair value of plan assets and actuarial gains and losses being recognized in earnings faster than under our previous methods of accounting. We believe the new methods of accounting are preferable as these methods recognize the effects of plan investment performance, interest rate changes, and changes in actuarial assumptions as a component of earnings in the year in which they occur. These changes have been reported through retrospective application of the new accounting methods to all periods presented. The remaining components of pension/postretirement expense, primarily service and interest costs and expected return on plan assets, will continue to be recorded on a quarterly basis. See Note 10 for further discussion of our pension and postretirement benefits and Note 19 for the impact of the above changes on our consolidated financial statements for the years ended December 31, 2013, 2012 and 2011.
Foreign Currency Translation and Transactions	Foreign Currency Translation and Transactions — The financial statements of our foreign subsidiaries are translated into U.S. dollars in accordance with the Foreign Currency Matters Topic of the Financial Accounting Standards Board Codification ("Codification" or "ASC"). Balance sheet accounts are translated at the current rate at the end of each period and income statement accounts are translated at the average rate for each period. Gains and losses on foreign currency translations are reflected as a separate component of shareholders' equity and other comprehensive income (loss). Foreign currency transaction gains and losses, as well as gains and losses related to foreign currency protection contracts and currency forward embedded derivatives, are included in "Other income (expense), net," with the related net losses totaling $15.6, $12.4 and $41.4 in 2013, 2012 and 2011, respectively.
Cash Equivalents	Cash Equivalents — We consider highly liquid money market investments with original maturities of three months or less at the date of purchase to be cash equivalents.
Revenue Recognition	Revenue Recognition — We recognize revenues from product sales upon shipment to the customer (e.g., FOB shipping point) or upon receipt by the customer (e.g., FOB destination), in accordance with the agreed upon customer terms. Revenues from service contracts and long-term maintenance arrangements are recognized on a straight-line basis over the agreement period. Sales with FOB destination terms are primarily to power transformer industry customers. Sales to distributors with return rights are recognized upon shipment to the distributor with expected returns estimated and accrued at the time of sale. The accrual considers restocking charges for returns and in some cases the distributor must issue a replacement order before the return is authorized. Actual return experience may vary from our estimates. We recognize revenues separately for arrangements with multiple deliverables that meet the criteria for separate units of accounting as defined by the Revenue Recognition Topic of the Codification. The deliverables under these arrangements typically include hardware and software components, installation, maintenance, extended warranties and software upgrades. Amounts allocated to each element are based on its objectively determined fair value, such as the sales price of the product or service when it is sold separately, competitor prices for similar products or our best estimate. The hardware and software components are usually recognized as revenue contemporaneously, as both are required for essential functionality of the products, with the installation being recognized upon completion. Revenues related to maintenance, extended warranties and software upgrades are recognized on a pro-rata basis over the coverage period. We offer sales incentive programs primarily to effect volume rebates and promotional and advertising allowances. These programs are only significant to one of our business units. The liability for these programs, and the resulting reduction to reported revenues, is determined primarily through trend analysis, historical experience and expectations regarding customer participation. Amounts billed for shipping and handling are included in revenues. Costs incurred for shipping and handling are recorded in cost of products sold. Taxes assessed by governmental authorities that are directly imposed on a revenue-producing transaction between a seller and a customer are presented on a net basis (excluded from revenues) in our consolidated statements of operations. In addition, certain of our businesses, primarily within the Flow Technology and Thermal Equipment and Services reportable segments, also recognize revenues from long-term construction/installation contracts under the percentage-of-completion method of accounting. The percentage-of-completion is measured principally by the percentage of costs incurred to date for each contract to the estimated total costs for such contract at completion. We recognize revenues for similar short-term contracts using the completed-contract method of accounting. Provisions for any estimated losses on uncompleted long-term contracts are made in the period in which such losses are determined. In the case of customer change orders for uncompleted long-term contracts, estimated recoveries are included for work performed in forecasting ultimate profitability on certain contracts. Due to uncertainties inherent in the estimation process, it is possible that completion costs, including those arising from contract penalty provisions and final contract settlements, may be revised in the near-term. Such revisions to costs and income are recognized in the period in which the revisions are determined. Costs and estimated earnings in excess of billings arise when revenues have been recorded but the amounts have not been billed under the terms of the contracts. These amounts are recoverable from customers upon various measures of performance, including achievement of certain milestones, completion of specified units or completion of the contract. Claims related to long-term contracts are recognized as revenue only after we have determined that collection is probable and the amount can be reliably estimated. Claims made by us involve negotiation and, in certain cases, litigation or other dispute-resolution processes. In the event we incur litigation or other dispute-resolution costs in connection with claims, such costs are expensed as incurred, although we may seek to recover these costs. Claims against us are recognized when a loss is considered probable and amounts are reasonably estimable.
Research and Development Costs	Research and Development Costs — We expense research and development costs as incurred. We charge costs incurred in the research and development of new software included in products to expense until technological feasibility is established. After technological feasibility is established, additional eligible costs are capitalized until the product is available for general release. We amortize these costs over the economic lives of the related products and include the amortization in cost of products sold. We perform periodic reviews of the recoverability of these capitalized software costs. At the time we determine that capitalized amounts are not recoverable based on the estimated cash flows to be generated from the applicable software, we write off any unrecoverable capitalized amounts. We expensed research activities relating to the development and improvement of our products of $44.7, $46.0 and $41.1 in 2013, 2012 and 2011, respectively.
Property, Plant and Equipment	Property, Plant and Equipment — Property, plant and equipment ("PP&E") is stated at cost, less accumulated depreciation. We use the straight-line method for computing depreciation expense over the useful lives of PP&E, which do not exceed 40 years for buildings and range from 3 to 15 years for machinery and equipment. Depreciation expense, including amortization of capital leases, was $81.8, $73.5 and $59.9 for the years ended December 31, 2013, 2012 and 2011, respectively. Leasehold improvements are amortized over the life of the related asset or the life of the lease, whichever is shorter. Interest is capitalized on significant construction or installation projects. Interest capitalized during 2012 and 2011 totaled $0.5 and $1.3, respectively. No interest was capitalized during 2013.
Income Taxes	Income Taxes — We account for our income taxes based on the requirements of the Income Taxes Topic of the Codification, which includes an estimate of the amount of taxes payable or refundable for the current year and deferred tax liabilities and assets for the future tax consequences of events that have been recognized in our consolidated financial statements or tax returns. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. We periodically assess the realizability of deferred tax assets and the adequacy of deferred tax liabilities, including the results of local, state, federal or foreign statutory tax audits or estimates and judgments used.
Derivative Financial Instruments	Derivative Financial Instruments — We use foreign currency forward contracts ("FX forward contracts") to manage our exposures to fluctuating currency exchange rates, and forward contracts to manage the exposure on forecasted purchases of commodity raw materials ("commodity contracts"). We have used interest rate protection agreements ("Swaps") to manage our exposures to fluctuating interest rate risk on variable rate debt. Derivatives are recorded on the balance sheet and measured at fair value. For derivatives designated as hedges of the fair value of assets or liabilities, the changes in fair values of both the derivatives and the hedged items are recorded in current earnings. For derivatives designated as cash flow hedges, the effective portion of the changes in fair value of the derivatives is recorded in AOCI and subsequently recognized in earnings when the hedged items impact earnings. Changes in the fair value of derivatives not designated as hedges, and the ineffective portion of cash flow hedges, are recorded in current earnings. We do not enter into financial instruments for speculative or trading purposes. For those transactions that are designated as cash flow hedges, on the date the derivative contract is entered into, we document our hedge relationship, including identification of the hedging instruments and the hedged items, as well as our risk management objectives and strategies for undertaking the hedge transaction. We also assess, both at inception and quarterly thereafter, whether such derivatives are highly effective in offsetting changes in the fair value of the hedged item. See Notes 13 and 16 for further information. Cash flows from hedging activities are included in the same category as the items being hedged, which is primarily operating activities.
Use of Estimates
Accounts Receivable Allowances	Accounts Receivable Allowances — We provide allowances for estimated losses on uncollectible accounts based on our historical experience and the evaluation of the likelihood of success in collecting specific customer receivables. In addition, we maintain allowances for customer returns, discounts and invoice pricing discrepancies, with such allowances primarily based on historical experience.
Inventory	Inventory — We estimate losses for excess and/or obsolete inventory and the net realizable value of inventory based on the aging and historical utilization of the inventory and the evaluation of the likelihood of recovering the inventory costs based on anticipated demand and selling price.
Impairment of Long-Lived Assets and Intangible Assets Subject to Amortization	Impairment of Long-Lived Assets and Intangible Assets Subject to Amortization — We continually review whether events and circumstances subsequent to the acquisition of any long-lived assets, or intangible assets subject to amortization, have occurred that indicate the remaining estimated useful lives of those assets may warrant revision or that the remaining balance of those assets may not be fully recoverable. If events and circumstances indicate that the long-lived assets should be reviewed for possible impairment, we use projections to assess whether future cash flows on an undiscounted basis related to the assets are likely to exceed the related carrying amount. We will record an impairment charge to the extent that the carrying value of the assets exceed their fair values as determined by valuation techniques appropriate in the circumstances, which could include the use of similar projections on a discounted basis. In determining the estimated useful lives of definite-lived intangibles, we consider the nature, competitive position, life cycle position, and historical and expected future operating cash flows of each acquired asset, as well as our commitment to support these assets through continued investment and legal infringement protection.
Goodwill and Indefinite-Lived Intangible Assets	Goodwill and Indefinite-Lived Intangible Assets — We test goodwill and indefinite-lived intangible assets for impairment annually during the fourth quarter and continually assess whether a triggering event has occurred to determine whether the carrying value exceeds the implied fair value. The fair value of reporting units is based generally on discounted projected cash flows, but we also consider factors such as comparable industry price multiples. We employ cash flow projections that we believe to be reasonable under current and forecasted circumstances, the results of which form the basis for making judgments about the carrying values of the reported net assets of our reporting units. Many of our businesses closely follow changes in the industries and end markets that they serve. Accordingly, we consider estimates and judgments that affect the future cash flow projections, including principal methods of competition, such as volume, price, service, product performance and technical innovations, as well as estimates associated with cost reduction initiatives, capacity utilization and assumptions for inflation and foreign currency changes. Actual results may differ from these estimates under different assumptions or conditions. See Note 8 for further information, including discussion of impairment charges recorded in 2013, 2012 and 2011.
Accrued Expenses	Accrued Expenses — We make estimates and judgments in establishing accruals as required under GAAP.
Legal	Legal — It is our policy to accrue for estimated losses from legal actions or claims when events exist that make the realization of the losses probable and they can be reasonably estimated. We do not discount legal obligations or reduce them by anticipated insurance recoveries.
Environmental Remediation Costs	Environmental Remediation Costs — We expense costs incurred to investigate and remediate environmental issues unless they extend the economic useful lives of related assets. We record liabilities when it is probable that an obligation has been incurred and the amounts can be reasonably estimated. 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. We generally do not discount environmental obligations or reduce them by anticipated insurance recoveries.
Self-Insurance	Self-Insurance — We are self-insured for certain of our workers' compensation, automobile, product, general liability, disability and health costs, and we maintain adequate accruals to cover our retained liabilities. Our accruals for self-insurance liabilities are based on claims filed and an estimate 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; however, this insurance may be insufficient or unavailable (e.g., because of insurer insolvency) to protect us against potential loss exposures. The key assumptions considered in estimating the ultimate cost to settle reported claims and the estimated costs associated with incurred but not yet reported claims include, among other things, our historical and industry claims experience, trends in health care and administrative costs, our current and future risk management programs, and historical lag studies with regard to the timing between when a claim is incurred and reported.
Warranty	Warranty — In the normal course of business, we issue product warranties for specific products and provide for the estimated future warranty cost in the period in which the sale is recorded. We provide for the estimate of warranty cost based on contract terms and historical warranty loss experience that is periodically adjusted for recent actual experience. Because warranty estimates are forecasts that are based on the best available information, claims costs may differ from amounts provided. In addition, due to the seasonal fluctuations at certain of our businesses, the timing of warranty provisions and the usage of warranty accruals can vary period to period. We make adjustments to initial obligations for warranties as changes in the obligations become reasonably estimable.
Income Taxes	Income Taxes — We perform reviews of our income tax positions on a continuous basis and accrue for potential uncertain tax positions in accordance with the Income Taxes Topic of the Codification. Accruals for these uncertain tax positions are classified as "Income taxes payable" and "Deferred and other income taxes" in the accompanying consolidated balance sheets based on an expectation as to the timing of when the matter will be resolved. As events change or resolutions occur, these accruals are adjusted, such as in the case of audit settlements with taxing authorities. These reviews also entail analyzing the realization of deferred tax assets. When we believe that it is more likely than not that we will not realize a benefit for a deferred tax asset, we establish a valuation allowance against it. For tax positions where it is more likely than not that a tax benefit will be sustained, we record the largest amount of tax benefit with a greater than 50% likelihood of being realized upon ultimate settlement with a taxing authority, assuming such authority has full knowledge of all relevant information.
Employee Benefit Plans	Employee Benefit Plans — Defined benefit plans cover a portion of our salaried and hourly employees, including certain employees in foreign countries. As discussed in Note 1, in the fourth quarter of 2013, we elected to change our accounting methods for recognizing changes in the fair value of plan assets and actuarial gains and losses associated with our pension and postretirement benefit plans. Under our new preferable accounting methods, we recognize changes in the fair value of plan assets and actuarial gains and losses in earnings during the fourth quarter of each year as a component of net periodic benefit expense. These changes have been reported through retrospective application of the new accounting methods to all periods reported. The remaining components of pension/postretirement expense, primarily service and interest costs and expected return on plan assets, will be recorded on a quarterly basis. See Note 10 for further discussion of our pension and postretirement benefits and Note 19 for the impact of the above changes on our consolidated financial statements for the years ended December 31, 2013, 2012 and 2011. We derive pension expense from an actuarial calculation based on the defined benefit plans' provisions and our assumptions regarding discount rate and rate of increase in compensation levels. We determine the discount rate for our more significant U.S. plans by matching the expected projected benefit obligation cash flows of the plans to a yield curve that is representative of long-term, high-quality (rated AA or higher) fixed income debt instruments as of the measurement date. For our other plans, we determine the discount rate based on representative bond indices. The rate of increase in compensation levels is established based on our expectations of current and foreseeable future increases in compensation. We also consult with independent actuaries in determining these assumptions.
Acquisitions and Discontinued Operations
Business Acquisitions	The consolidated statements of operations include the results of each acquired business since the date of acquisition. The assets acquired and liabilities assumed are recorded at estimates of fair values as determined by us based on information available at the acquisition date. We consider a number of factors, including third-party valuations or appraisals, when making these determinations. We will recognize additional assets or liabilities if new information is obtained during the measurement period about facts and circumstances that existed as of the acquisition date that, if known, would have resulted in the recognition of those assets and liabilities as of that date. The measurement period will not exceed one year from the acquisition date. Refer to Note 8 for additional disclosure on the purchase price adjustments of the following acquisitions.
Discontinued Operations	Discontinued Operations We report businesses or asset groups as discontinued operations when, among other things, we terminate the operations of the business or asset group, commit to a plan to divest the business or asset group or we actively begin marketing the business or asset group, and the sale of the business or asset group is deemed probable within the next twelve months.
Environmental Matters
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 the aggregate, on our business, financial condition, results of operations or cash flows. At December 31, 2013, we had liabilities for site investigation and/or remediation at 94 sites (95 sites at December 31, 2012) 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 generally do not discount our environmental accruals and do not reduce them by anticipated insurance recoveries. 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.

Under our historical methods, we would have recorded pension/postretirement expense of $407.0 during the fourth quarter of 2013, which would have included a charge of $399.4 associated primarily with the November 2013 transfer of the pension obligations of the retirees under the Plan to Mass Mutual (see Notes 1 and 10 for additional details). Under our new methods of recording pension and postretirement expense, we recorded pension income of $5.0 during the fourth quarter of 2013.

(1): "As Revised and Restated" for 2012 and 2011 represents amounts as previously reported in our 2012 Annual Report on Form 10-K (as amended), revised and restated to reflect (i) the reclassification of certain prior period amounts, including the results of discontinued operations (see Note 4), as well as (ii) the correction of prior period misstatements within our income tax accounts (see Notes 1, 11 and 18 for further information).
(2): Reflects amounts we would have reported had we not changed our accounting methods for recognizing changes in the fair value of plan assets and actuarial gains and losses.
(3): Reflects amounts reported in the accompanying consolidated financial statements as of and for the years ended December 31, 2013, 2012 and 2011.
(4): Under our historical methods of accounting for our pension and postretirement benefit plans, our pension and postretirement benefit expense for 2013 would have been a pre-tax charge of $425.6 as compared to pension and postretirement benefit income of $17.7 recognized under our new methods. The pre-tax charge under our historical methods reflects the effects of a $399.4 charge that would have been recognized as a result of the settlement of approximately 61% of the Plan's projected benefit obligation as of November 12, 2013, due primarily to the transfer of the retiree pension obligations of the Plan to Mass Mutual, as previously described.

- Definition

Assets, usually stocks, bonds, and other investments, that have been segregated and restricted (usually in a trust) to provide benefits, at their fair value as of the measurement date. Plan assets include amounts contributed by the employer (and by employees for a contributory plan) and amounts earned from investing the contributions, less benefits paid. If a plan has liabilities other than for benefits, those non-benefit obligations may be considered as reductions of plan assets.
