ACQUISITIONS AND DISCONTINUED OPERATIONS

ACQUISITIONS AND DISCONTINUED OPERATIONS

(3) ACQUISITIONS AND DISCONTINUED OPERATIONS

Acquisitions

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

In March 2011, our Test and Measurement segment completed the acquisition of substantially all of the assets of Teradyne Inc.’s Diagnostic Solutions business (“DS”), a global supplier of diagnostic solutions for transportation OEMs and automotive dealerships, for a purchase price of $40.2. DS had revenues of approximately $42.0 in the twelve months prior to the date of acquisition.

In July 2010, our Flow Technology segment completed the acquisition of the Anhydro business (“Anhydro”), a global supplier of liquid concentration equipment, powder processing solutions, and dewatering plants and equipment, for a purchase price of $59.1, net of cash acquired of $10.9. Anhydro had revenues of approximately $71.0 in the twelve months prior to the date of acquisition.

In April 2010, our Industrial Products and Services segment completed the acquisition of Torque Tension Systems Ltd. (“TTS”), a global supplier of hydraulic torque wrench and tensioner tool products, for a purchase price of $15.7, net of cash acquired of $2.4. TTS had revenues of approximately $9.0 in the twelve months prior to the date of acquisition.

In February 2010, our Flow Technology segment completed the acquisition of Gerstenberg Schröder A/S (“Gerstenberg”), a designer, manufacturer, installer and servicer of processing systems and components serving the global food industry, for a purchase price of $30.9, net of cash acquired of $3.5 and including debt assumed of $3.9. Gerstenberg had revenues of approximately $57.0 in the twelve months prior to the date of acquisition.

The pro forma effects of the completed acquisitions were not material, individually or in the aggregate, to our results of operations.

The assets acquired and liabilities assumed were recorded at preliminary estimates of fair value as determined by management, based on information available at the acquisition date and on current assumptions as to future operations, and are subject to change during the measurement period upon the completion of acquisition accounting, including the finalization of asset valuations and any working capital settlements.

On August 24, 2011, we entered into an agreement to purchase Clyde Union (Holdings) S.A.R.L (“Clyde Union”), a global supplier of pump technologies that are utilized in oil and gas processing, power generation and other industrial applications. On November 1, 2011, we executed an amendment to that agreement. Under the amended agreement, the purchase price (payable in cash) is equal to the sum of (i) an initial payment of 565.0 British Pounds (“GBP”) plus (ii) an earn-out payment equal to 11.8 times the amount by which the March 31, 2012 Group Earnings Before Interest, Taxes, Depreciation and Amortization (“EBITDA”) for the trailing twelve months (Group EBITDA terms are as defined in the related share purchase agreement) is greater than 47.881 GBP, if any, and (iii) a separate earn-out payment equal to:

Annual 2012 Group EBITDA less Earn-Out Threshold
10.0 GBP	x	(185.0 GBP less any payment made under (ii) above).

The Earn-Out Threshold is 65.0 GBP unless March 31, 2012 Group EBITDA for the trailing twelve months is less than 47.881 GBP, in which case it is 112.881 GBP less the amount of the trailing twelve month March 31, 2012 Group EBITDA.

In no event shall either earn-out payment be less than zero nor shall the aggregate earn-out payments exceed 185.0 GBP.

Consummation of the transaction is subject to certain closing conditions, including the receipt of required regulatory approvals, with the closing targeted to occur by December 22, 2011.

Clyde Union has approximately 2,000 employees, is based in Glasgow, United Kingdom, and operates eight manufacturing facilities and 25 service centers around the world. We expect that the acquisition of Clyde Union will expand our market position within, and create a global power and energy platform for, our Flow Technology segment.

We plan to finance the acquisition with available cash and committed senior secured financing. See Note 10 for further

details on the senior secured financing.

On October 31, 2011, our Flow Technology segment completed the acquisition of e&e Verfahrenstechnik GmbH, 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 12.3 Euros, net of cash assumed of 2.2 Euros, with an additional potential earn-out of 3.5 Euros.

Discontinued Operations

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

We report businesses or asset groups as discontinued operations when, among other things, we commit to a plan to divest the business or asset group, actively begin marketing the business or asset group, and when the sale of the business or asset group is deemed probable within the next twelve months. The following businesses, which have been sold, met these requirements, and therefore have been reported as discontinued operations for the periods presented:

Business	Quarter Discontinued	Quarter Sale Closed
Cooling Spain Packaging business (“Cooling Spain”)	Q4 2010	Q4 2010
P.S.D., Inc. (“PSD”)	Q2 2009	Q1 2010

Cooling Spain — Sold for cash consideration of one Euro (exclusive of cash transferred with the business of $2.3), resulting in a loss, net of taxes, of $1.9 during the fourth quarter of 2010. During the first quarter of 2011, we recorded a net charge of $0.1 to “Gain (loss) on disposition of discontinued operations, net of tax” within our condensed consolidated statements of operations in connection with adjustments to certain liabilities that we retained.

PSD — Sold for cash consideration of $3.0, resulting in a gain, net of taxes, of $3.6 during the first quarter of 2010.

In addition to the businesses discussed above, we recognized a net gain of $0.4 and $1.3 during the three and nine months ended October 1, 2011, respectively, a net loss of $0.1 and a net gain of $1.2 during the three and nine months ended October 2, 2010, respectively, resulting from adjustments to gains/losses on sales from previously discontinued businesses. Refer to the consolidated financial statements contained in our 2010 Annual Report on Form 10-K for the disclosure of all discontinued businesses during the 2008 through 2010 period.

During the second quarter of 2010, the field examinations of our 2006 and 2007 federal income tax returns were completed by the Internal Revenue Service (“IRS”). In connection with the completion of these examinations, we reduced our liability for uncertain tax positions and recognized an income tax benefit of $7.3 to “Gain (loss) on disposition of discontinued operations, net of tax” associated with a business previously disposed of and reported as a discontinued operation.

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

For the three and nine months ended October 1, 2011 and October 2, 2010, income (loss) from discontinued operations and the related income taxes are shown below:

	Three months ended						Nine months ended
	October 1,			October 2,			October 1,			October 2,
	2011			2010			2011			2010
Income (loss) from discontinued operations	$	0.7		$	(0.1	)	$	(2.0	)	$	1.9
Income tax (provision) benefit	(0.3		)	0.1			3.2			9.9
Income from discontinued operations, net	$	0.4		$	—		$	1.2		$	11.8

For the three and nine months ended October 1, 2011 and October 2, 2010, results of operations for our businesses reported as discontinued operations were as follows:

	Three months ended				Nine months ended
	October 1,		October 2,		October 1,		October 2,
	2011		2010		2011		2010
Revenues	$	—	$	1.4	$	—	$	5.2
Pre-tax income (loss)	—		0.1		—		(0.3		)

There were no assets or liabilities attributable to discontinued operations at October 1, 2011 and December 31, 2010.

Other Intangibles

Identifiable intangible assets comprised the following:

	October 1, 2011							December 31, 2010
	Gross Carrying Value		Accumulated Amortization			Net Carrying Value		Gross Carrying Value		Accumulated Amortization			Net Carrying Value
Intangible assets with determinable lives:

Technology	118.0		(29.8		)	88.2		116.7		(23.3		)	93.4

Trademarks with indefinite lives (1)	407.5		—			407.5		413.1		—			413.1
Total	$	845.1	$	(129.5	)	$	715.6	$	829.5	$	(110.0	)	$	719.5

(1) Balance at October 1, 2011 reflects impairment charges recorded during the second quarter of 2011 associated with businesses within our Thermal Equipment and Services and Industrial Products and Services segments of $7.5 and $0.8, respectively.

Estimated annual amortization expense related to these intangible assets is $32.6 in 2011, $28.5 in 2012, $26.5 in 2013, $25.8 in 2014 and $23.9 in 2015.

At October 1, 2011, the net carrying value of intangible assets with determinable lives consisted of $161.4 in the Flow Technology segment, $75.9 in the Test and Measurement segment, $59.5 in the Thermal Equipment and Services segment, and $11.3 in the Industrial Products and Services segment. Trademarks with indefinite lives consisted of $208.3 in the Flow Technology segment, $54.3 in the Test and Measurement segment, $130.7 in the Thermal Equipment and Services segment, and $14.2 in the Industrial Products and Services segment.

We annually test the recoverability of our goodwill and indefinite-lived intangible assets during the fourth quarter based on a measurement date as of the end of the third quarter. In addition, we test such assets for impairment on a more frequent basis if there are indications of potential impairment. Based on our annual impairment testing during the fourth quarter of 2010, our SPX Heat Transfer Inc. reporting unit had an estimated fair value that was comparable to the carrying value of its net assets. In the second quarter of 2011, SPX Heat Transfer Inc. experienced an additional decline in its revenues and profitability, furthering a trend that began late in the first quarter of 2011, in comparison to (i) recent historical results and (ii) expected results for the period, due to the challenging conditions within the U.S. power market. Although we expect financial results for the reporting unit to rebound, the projections of future discounted cash flows as of the end of the second quarter of 2011 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 Inc.’s goodwill ($17.2) and indefinite-lived intangible assets ($7.5). After the $24.7 impairment charge, SPX Heat Transfer Inc. had goodwill and indefinite-lived intangible assets of $3.6 and $22.6, respectively.

Net periodic postretirement benefit expense of continuing operations	$	2.6		$	3.1		$	8.0		$	8.4

During the first nine months of 2011, we made contributions of approximately $10.6 to our foreign and qualified domestic pension plans, of which $1.4 related to businesses classified as discontinued operations.

An increase in the number of inactive participants in one of our domestic pension plans resulted in almost all of the plan participants being inactive. Accordingly, in the first quarter of 2011, we began amortizing the unrecognized gains/losses over the average remaining life expectancy of the inactive participants as opposed to the average remaining service period of the active participants. This change resulted in a reduction to pension expense of approximately $5.0 and $15.0 during the three and nine months ended October 1, 2011, respectively.

Total long-term debt	$	1,110.5								$	1,114.8

(1) In August 2010, we issued $600.0 of 6.875% senior notes that mature in 2017. The proceeds from the issuance were used to repay the remaining balance ($562.5) under the term loan of our then-existing senior credit facilities. In connection with the early repayment of the term loan, we also terminated the related interest rate protection agreements. Cost associated with the early repayment of the term loan and the termination of the interest rate protection agreements totaled $25.6, including $1.1 for the write-off of deferred financing costs, $0.2 for fees related to the early repayment of the term loan, and $24.3 to settle the interest rate protection agreements.

(2) These notes were redeemed in full in January 2011.

(3) These notes were redeemed in full in June 2011.

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

(5) Includes balances under a purchase card program of $38.8 and $36.1 at October 1, 2011 and December 31, 2010, respectively.

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

New Senior Credit Facilities

On June 30, 2011, we entered into new senior credit facilities with a syndicate of lenders that replaced our then-existing senior credit facilities. The new senior credit facilities provide for committed senior secured financing of $1,800.0, consisting of the following (each with a final maturity of June 30, 2016):

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

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

· A participation foreign credit instrument facility, available for performance letters of credit and guarantees, in an aggregate principal amount in various currencies up to the equivalent of $1,100.0; and

· A bilateral foreign credit instrument facility, available for performance letters of credit and guarantees, in an aggregate principal amount in various currencies up to the equivalent of $100.0.

In addition, the lenders in the syndicate under the new senior credit facilities generally are comparable to those that existed for the previous senior credit facilities.

The new senior credit facilities allow additional commitments 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 of $1,000.0.

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 new 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 foreign credit instruments, including bank undertakings to support our foreign operations.

At October 1, 2011, we had $83.8 and $654.5 of outstanding letters of credit issued under our revolving credit and our foreign trade facilities of our senior credit agreement, respectively. In addition, we had $2.9 of letters of credit outstanding under separate arrangements in China and South Africa.

The interest rates applicable to loans under our new 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 rate plus 1.0%) or (ii) a reserve-adjusted LIBOR rate for dollars (Eurodollar) plus, in each case, an applicable margin percentage, which varies based on our 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) at the date of determination to consolidated adjusted EBITDA for the four fiscal quarters ended on such date). We may elect interest periods of one, two, three or six months for Eurodollar borrowings. The fees charged and the interest rate margins applicable to Eurodollar and alternate base rate loans are (all on a per annum basis) as follows:

Consolidated Leverage Ratio	Domestic Revolving Commitment Fee		Global Revolving Commitment Fee		Letter of Credit Fee		Foreign Credit Commitment Fee and Bilateral Foreign Credit Fee		Foreign Credit Instrument Fee and Bilateral Foreign Credit Fee		LIBOR Rate Loans		ABR Loans

Greater than or equal to 3.00 to 1.0	0.40	%	0.40	%	2.00	%	0.40	%	1.25	%	2.00	%	1.00	%
Between 2.00 to 1.0 and 3.00 to 1.0	0.35	%	0.35	%	1.875	%	0.35	%	1.125	%	1.875	%	0.875	%
Between 1.50 to 1.0 and 2.00 to 1.0	0.30	%	0.30	%	1.75	%	0.30	%	1.00	%	1.75	%	0.75	%
Between 1.00 to 1.0 and 1.50 to 1.0	0.275	%	0.275	%	1.50	%	0.275	%	0.875	%	1.50	%	0.50	%
Less than 1.00 to 1.0	0.25	%	0.25	%	1.25	%	0.25	%	0.75	%	1.25	%	0.25	%

The weighted-average interest rate of our outstanding borrowings under our senior credit facilities was approximately 2.3% at October 1, 2011.

The fees for bilateral foreign credit commitments are as specified above for foreign credit commitments, 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 0.20% per annum, respectively.

Our new 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 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.

We may voluntarily prepay loans under our new 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 new 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 new 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 “Ba2” or less (or not rated) by Moody’s and “BB” or less (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 and their assets. If our corporate credit rating is “Baa3” or better by Moody’s or “BBB-” or better by S&P and no defaults exist, then all collateral security will be released and the indebtedness under our senior credit facilities will be unsecured.

Our new senior credit facilities require that we maintain:

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

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

Our new 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 new senior credit facilities also contain customary representations, warranties, affirmative covenants, and events of default.

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

During the third quarter of 2011, we were in compliance with all covenant provisions of our new senior credit facilities and our senior notes.

Modifications to Senior Credit Facilities

On October 5, 2011, we modified our existing senior credit facilities in order to provide additional committed senior secured financing in an aggregate amount of $800.0, consisting of the following term loans (collectively, the “Term Loans”):

· A delayed draw incremental term loan, in an aggregate principal amount of $300.0, repayable in full on the date that is 18 months after the date of its funding; and

· A delayed draw incremental term loan, in an aggregate principal amount of $500.0, repayable in quarterly installments (with annual repayments, as a percentage of the initial principal amount, of 0% for 2011 and 2012, 5% for 2013, 15% for 2014 and 20% for 2015, together with a single quarterly payment of 5% at the end of the first fiscal quarter of 2016), with the remaining balance repayable in full on June 30, 2016.

We intend to use the proceeds of the Term Loans to finance the Clyde Union acquisition and also may repay debt outstanding

at the time of funding.

We may borrow against the Term Loans in a single drawing on or before December 31, 2011. If we do not consummate the Clyde Union acquisition substantially contemporaneously with such borrowing, we are required to maintain the proceeds of the Term Loans in a cash collateral account with the administrative agent until used for the Clyde Union acquisition. The ability to draw on the Term Loans is subject to the satisfaction of customary conditions, including absence of defaults and accuracy in material respects of representations and warranties. We are required to repay the Term Loans in full if we do not consummate the Clyde Union acquisition.

The interest rates applicable to the Term Loans are calculated in a manner consistent with our existing senior credit facilities. The interest rate margins applicable to LIBOR and alternate base rate Term Loans are (all on a per annum basis) as follows:

Consolidated Leverage Ratio	LIBOR Rate Loans		ABR Loans

Greater than or equal to 3.00 to 1.0	2.250	%	1.250	%
Between 2.00 to 1.0 and 3.00 to 1.0	2.125	%	1.125	%
Between 1.50 to 1.0 and 2.00 to 1.0	2.000	%	1.000	%
Between 1.00 to 1.0 and 1.50 to 1.0	1.750	%	0.750	%
Less than 1.00 to 1.0	1.500	%	0.500	%

We will pay an upfront fee in an amount equal to an approximate average of 0.5% of the commitment of each lender providing a portion of the Term Loans. In addition, we are required to pay a commitment fee in an amount equal to 0.275% per annum of the daily unused amount of the commitment of the Term Loans, which will accrue from October 5, 2011 through the date on which Term Loan amounts are borrowed (or the commitment is terminated).

Except as noted below, the Term Loans require mandatory prepayments in circumstances consistent with the existing credit facilities. Mandatory prepayments will be applied, first, to repay 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 after the Term Loans and any such incremental term loans have been repaid in full, and second, to repay 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). As with the existing credit facilities, 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, upon the incurrence of unsecured indebtedness in the form of a private or public note or bond issuance, the net proceeds of such indebtedness will be applied to the extent necessary to repay in full any amounts outstanding under the $300.0 term loan.

Consistent with the existing senior credit facilities, we may voluntarily prepay the Term Loans, in whole or in part, without premium or penalty. Any prepayment of the Term Loans will be subject to reimbursement of the lenders’ breakage costs in the case of a prepayment of LIBOR rate borrowings other than on the last day of the relevant interest period.

The Term Loans are guaranteed, secured, and subject to representations, warranties, covenants and events of default in a manner consistent with the existing senior credit facilities.

The existing credit facilities include a foreign trade facility and bilateral foreign trade facilities, each available for performance letters of credit and guarantees, in an aggregate principal amount in various currencies up to the equivalent of $1,100.0 and $100.0, respectively. As part of our modification of the existing senior credit facilities, we obtained a $100.0 commitment for an additional bilateral foreign trade facility, thereby increasing the total bilateral trade facilities to an aggregate principal amount in various currencies up to the equivalent of $200.0. Effective upon this increase in the bilateral foreign trade facilities, we reduced our foreign credit commitments on a pro rata basis under the foreign trade facility by an aggregate amount of $100.0, thereby reducing the foreign trade facilities to an aggregate principal amount in various currencies up to the equivalent of $1,000.0.

DERIVATIVE FINANCIAL INSTRUMENTS

DERIVATIVE FINANCIAL INSTRUMENTS

DERIVATIVE FINANCIAL INSTRUMENTS

(11) DERIVATIVE FINANCIAL INSTRUMENTS

Interest Rate Swaps

Prior to the August 2010 repayment of our variable rate term loan, we maintained interest rate protection agreements (“Swaps”) to hedge the associated interest rate risk. These Swaps, which we designated and accounted for as cash flow hedges, effectively converted the majority of the borrowings under our variable rate term loan to a fixed rate of 4.795% plus the applicable margin. In connection with the repayment of our term loan, we terminated all our Swaps resulting in a cash payment of $26.9 (including $2.6 of accrued interest) and a charge to earnings of $24.3 during the three months ended October 2, 2010.

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 the impact of any currency fluctuations. Our principal currency exposures relate to the Euro, Chinese Yuan, South African Rand and British Pound.

From time to time, we enter into currency protection agreements (“FX forward contracts”) to manage the exposure on contracts with forecasted transactions denominated in non-functional currencies and to manage the risk of transaction gains and losses associated with assets/liabilities denominated in currencies other than the functional currency of certain subsidiaries. In addition, some of our contracts contain currency forward embedded derivatives (“FX embedded derivatives”), as the currency of exchange is not “clearly and closely” related to the functional currency of either party to the transaction. Certain of our FX forward contracts are designated as cash flow hedges, as deemed appropriate. To the extent these derivatives are effective in offsetting the variability of the hedged cash flows, changes in the derivatives’ fair value are not included in current earnings, but are included in accumulated other comprehensive income (“AOCI”). These changes in fair value will subsequently be reclassified into earnings as a component of revenues or cost of goods sold, as applicable, when the forecasted transaction impacts earnings. In addition, if the forecasted transaction is no longer probable, the cumulative change in the derivatives’ fair value will be recorded as a component of “Other expense, net” in the period it occurs. To the extent that a previously designated hedging transaction is no longer an effective hedge, any ineffectiveness measured in the hedging relationship is recorded in earnings in the period it occurs. We had FX forward contracts with an aggregate notional amount of $844.5 and $199.5 outstanding as of October 1, 2011 and December 31, 2010, respectively. We had FX embedded derivatives with an aggregate notional amount outstanding of $107.9 and $200.9 at October 1, 2011 and December 31, 2010, respectively. The unrealized loss, net of taxes, recorded in AOCI related to FX forward contracts was $3.6 and $4.1 as of October 1, 2011 and December 31, 2010, respectively. We anticipate reclassifying approximately $1.8 of the unrealized loss to income over the next 12 months.

Beginning on August 30, 2011, we entered into FX forward contracts to hedge a significant portion of the purchase price of the Clyde Union acquisition, which, as previously noted, will be paid in GBP. From the inception of these agreements until October 1, 2011, the U.S. dollar strengthened against the GBP by approximately 5.0%. As a result, we recorded a non-cash charge during the third quarter of 2011 of $30.6, which was recorded in “Other expense, net” and based on the fair value of these agreements as of October 1, 2011.

Commodity Contracts

From time to time, we enter into commodity contracts to manage the exposure on forecasted purchases of commodity raw materials (“commodity contracts”). At October 1, 2011 and December 31, 2010, the outstanding notional amount of commodity contracts was 2.3 million and 1.8 million pounds of copper, respectively. We designate and account for these contracts as cash flow hedges and, to the extent these commodity contracts are effective in offsetting the variability of the forecasted purchases, the change in fair value is included in AOCI. We reclassify the AOCI associated with our commodity contracts to cost of products sold when the forecasted transaction impacts earnings. As of October 1, 2011 and December 31, 2010, the fair values of these contracts were $2.2 (current liability) and $1.0 (current asset), respectively. The unrealized gain (loss), net of taxes, recorded in AOCI was ($1.2) and $0.8 as of October 1, 2011 and December 31, 2010, respectively. We anticipate reclassifying the unrealized loss to income over the next 12 months.

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

Earnings Per Share

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

	Three months ended		Nine months ended
	October 1,	October 2,	October 1,	October 2,
	2011	2010	2011	2010
Weighted-average shares outstanding used in basic income per share	50.618	49.740	50.480	49.643
Dilutive Securities — Employee stock options and restricted stock units	0.186	0.705	0.559	0.579
Weighted-average number of common and dilutive securities used for calculating diluted income per share	50.804	50.445	51.039	50.222

The total number of stock options that were not included in the computation of diluted income per share because their exercise price was greater than the average market price of common shares was 0.128 and 0.093 for the three and nine months ended October 1, 2011, respectively, and 0.431 and 0.434 for the three and nine months ended October 2, 2010, respectively. For the three and nine months ended October 1, 2011, 1.316 and 0.443, respectively, and for the three and nine months ended October 2, 2010, 0.101 and 0.102, respectively, of unvested restricted stock units were excluded from the computation of diluted income per share because required market thresholds for vesting (as discussed below) were not met.

Stock-based Compensation

Under the 2002 Stock Compensation Plan, as amended in 2006 and 2011, the successor plan to the 1992 Stock Compensation Plan, up to 4.679 shares of our common stock were available for grant at October 1, 2011. The 2002 Stock Compensation Plan permits the issuance of new shares or shares from treasury upon the exercise of options, vesting of restricted stock units or granting of restricted stock. Each share of restricted stock and restricted stock unit granted reduces availability by 2.5 shares.

During the nine months ended October 1, 2011 and October 2, 2010, we classified excess tax benefits from stock-based compensation of $6.5 and $3.0, 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 exercise of employee stock options and other” within our condensed consolidated statements of cash flows.

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

We grant restricted stock to non-employee directors under the 2006 Non-Employee Directors’ Stock Incentive Plan (the “Directors’ Plan”). Under the Directors’ Plan, up to 0.030 shares of our common stock were available for grant at October 1, 2011. Restricted stock grants have a three-year vesting period based on SPX shareholder return versus the S&P 500 composite index and are subject to the same company performance thresholds for employee awards described in the preceding paragraph. Restricted stock that does not vest within the three-year vesting period in accordance with these performance requirements is forfeited.

Stock options may be granted to key employees in the form of incentive stock options or nonqualified stock options, generally vest ratably over three years, which vesting may be subject to performance criteria, and expire no later than 10 years from the date of grant. The option price per share may be no less than the fair market value of our common stock at the close of business 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.

The recognition of compensation expense for share-based awards, including stock options, is based on their grant date fair values. The fair value of each award is amortized over the lesser of the award’s requisite or derived service period, which is generally up to three years. Compensation expense related to restricted stock and restricted stock units totaled $34.5 and $25.4 for the nine months ended October 1, 2011 and October 2, 2010, respectively.

We use the Monte Carlo simulation model valuation technique to determine fair value of our restricted stock 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 and restricted stock unit award. We used the following assumptions in determining the fair value of the awards granted on March 1, 2011 and March 1, 2010:

	Annual expected stock price volatility		Annual expected dividend yield		Risk-free interest rate		Correlation between total shareholder return for SPX and S&P 500 Composite Index
March 1, 2011:
SPX Corporation	61.0	%	1.27	%	1.03	%	0.7559
S&P 500 Composite Index	30.3	%	n/a		1.03	%
March 1, 2010:
SPX Corporation	62.0	%	1.64	%	1.20	%	0.7250
S&P 500 Composite Index	30.8	%	n/a		1.20	%

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 the grant. The average risk-free interest rate is based on the one-year through three-year daily treasury yield curve rate as of the grant date.

The following table summarizes the restricted stock and restricted stock unit activity from December 31, 2010 through October 1, 2011:

	Unvested Restricted Stock and Restricted Stock Units		Weighted-Average Grant-Date Fair Value
Outstanding at December 31, 2010	1.516		$	50.97
Granted	0.832		62.73
Vested	(0.635	)	51.48
Forfeited	(0.263	)	67.87
Outstanding at October 1, 2011	1.450		54.35

As of October 1, 2011, there was $27.3 of unrecognized compensation cost related to restricted stock and restricted stock unit compensation arrangements. We expect this cost to be recognized over a weighted-average period of 1.5 years.

The following table shows stock option activity from December 31, 2010 through October 1, 2011:

	Shares		Weighted-Average Exercise Price
Outstanding at December 31, 2010	0.635		$	63.82
Exercised	(0.154	)	65.44
Forfeited	(0.113	)	90.93
Options outstanding and exercisable at October 1, 2011	0.368		54.87

The weighted-average remaining term, in years, of stock options outstanding and exercisable at October 1, 2011 was 0.8. The total number of in-the-money options exercisable on October 1, 2011 was 0.173. Aggregate intrinsic value (market value of stock less the option exercise price) represents the total pre-tax intrinsic value, based on our closing stock price on October 1, 2011, which would have been received by the option holders had all in-the-money option holders exercised their options as of that date. The aggregate intrinsic value of the options outstanding and exercisable at October 1, 2011 was $1.2. The aggregate intrinsic value of options exercised during the first nine months of 2011 was $2.5, while the related amount for the first nine months of 2010 was $1.1.

Accumulated Other Comprehensive Loss

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

	October 1, 2011			December 31, 2010
Foreign currency translation adjustment	$	253.0		$	223.2
Net unrealized losses on qualifying cash flow hedges, net of tax benefit of $3.2 and $2.2, respectively	(4.8		)	(3.3		)
Net unrealized gains (losses) on available-for-sale securities	(1.6		)	6.1
Pension and postretirement liability adjustment and other, net of tax benefit of $258.8 and $266.6, respectively (1)	(407.5		)	(418.6		)
Accumulated other comprehensive loss	$	(160.9	)	$	(192.6	)

(1) As of October 1, 2011 and December 31, 2010, includes $3.1 and $3.2, respectively, related to our share of the pension liability adjustment for EGS.

Common Stock in Treasury

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

During the nine months ended October 2, 2010, “Common stock in treasury” was decreased by the settlement of restricted stock units issued from treasury stock of $12.3 and increased by $5.1 for common stock that was surrendered by recipients of restricted stock as a means of funding the related minimum income tax withholding requirements.

Dividends

The dividends declared during each of the first three quarters of both 2011 and 2010 were $0.25 per share and totaled $12.7, $12.8 and $12.7 in the first, second and third quarters of 2011, respectively, and $12.5, $12.4 and $12.5 in the first, second and third quarters of 2010, respectively. Third quarter dividends were paid on October 4, 2011 and October 5, 2010.

CONTINGENCIES AND OTHER MATTERS

CONTINGENCIES AND OTHER MATTERS

(13) CONTINGENCIES AND OTHER MATTERS

General

Numerous claims, complaints and proceedings arising in the ordinary course of business, including those relating to litigation matters (e.g., class actions, derivative lawsuits and contracts, intellectual property and competitive claims), environmental matters, and risk management matters (e.g., product and general liability, automobile and workers’ compensation claims), have been filed or are pending against us and certain of our subsidiaries. Additionally, we may become subject to significant claims of which we are currently unaware, or the claims of which we are aware may result in us incurring a significantly greater liability than we anticipate. This may also be true in connection with past or future acquisitions. While we maintain property, cargo, auto, product, general liability, environmental, and directors’ and officers’ liability insurance and have acquired rights under similar policies in connection with acquisitions that we believe cover a portion of these claims, this insurance may be insufficient or unavailable (e.g., because of insurer insolvency) to protect us against potential loss exposures. In addition, we have increased our self-insurance limits over the past several years. While we believe we are entitled to indemnification from third parties for some of these claims, these rights may be insufficient or unavailable to protect us against potential loss exposures. However, we believe that our accruals related to these items are sufficient and that these items and our rights to available insurance and indemnity will be resolved without material effect, individually or in the aggregate, on our financial position, results of operations and cash flows. These accruals totaled $431.3 (including $368.6 for risk management matters) and $436.2 (including $366.1 for risk management matters) at October 1, 2011 and December 31, 2010, respectively. Of these amounts, $360.8 and $368.0 were included in “Other long-term liabilities” within our condensed consolidated balance sheets at October 1, 2011 and December 31, 2010, respectively, with the remainder included in “Accrued expenses.”

We had insurance recovery assets related to risk management matters of $319.0 and $320.0 at October 1, 2011 and December 31, 2010, respectively, included in “Other assets” within our condensed consolidated balance sheets.

Litigation Matters

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

Environmental Matters

Our operations and properties are subject to federal, state, local and foreign regulatory requirements relating to environmental protection. It is our policy to comply fully with all applicable requirements. As part of our effort to comply, we have a comprehensive environmental compliance program that includes environmental audits conducted by internal and external independent professionals, as well as regular communications with our operating units regarding environmental compliance requirements and anticipated regulations. Based on current information, we believe that our operations are in substantial compliance with applicable environmental laws and regulations, and we are not aware of any violations that could have a material adverse effect on our business, financial condition, results of operations or cash flows. We have liabilities for site investigation and/or remediation at 91 sites that we own or control. In addition, while we believe that we maintain adequate accruals to cover the costs of site investigation and/or remediation, we cannot provide assurance that new matters, developments, laws and regulations, or stricter interpretations of existing laws and regulations will not materially affect our business or operations in the future.

Our environmental accruals cover anticipated costs, including investigation, remediation, and operation and maintenance of clean-up sites. Our estimates are based primarily on investigations and remediation plans established by independent consultants, regulatory agencies and potentially responsible third parties. Accordingly, our estimates may change based on future developments, including new or changes in existing environmental laws or policies, differences in costs required to complete anticipated actions from estimates provided, future findings of investigation or remediation actions, or alteration to the expected remediation plans. It is our policy to realize a change in estimate once it becomes probable and can be reasonably estimated. We do not discount our environmental accruals and do not reduce them by anticipated insurance recoveries. We do 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, we have been notified that we are potentially responsible and have received other notices of potential liability pursuant to various environmental laws at 27 sites at which the liability has not been settled, and only 11 of which have been active in the past few years. These laws may impose liability on certain persons that are considered jointly and severally liable for the costs of investigation and remediation of hazardous substances present at these sites, regardless of fault or legality of the original disposal. These persons include the present or former owners or operators of the site and companies that generated, disposed of or arranged for the disposal of hazardous substances at the site. We are considered a “de minimis” potentially responsible party at most of the sites, and we estimate the aggregate probable remaining liability at these sites is immaterial.

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

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

We enter into consortium arrangements for certain projects within our Thermal Equipment and Services 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 October 1, 2011, our share of the aggregate contract value on open consortium arrangements was $398.8 (of which approximately 56% had been recognized as revenue), and the aggregate contract value on open consortium arrangements was $1,006.1. As of December 31, 2010, our share of the aggregate contract value on open consortium arrangements was $381.4 (of which approximately 45% had been recognized as revenue), and the aggregate contract value on open consortium arrangements was $948.7. At October 1, 2011 and December 31, 2010, we recorded liabilities of $3.4 and $3.2, respectively, representing the estimated fair value of our potential obligation under the joint and several liability provisions associated with the consortium arrangements.

U.S. Health Care Reform Legislation

In the first quarter of 2010, the Patient Protection and Affordable Care Act of 2010 (the “PPAC Act”) was enacted. As discussed in Note 14, the PPAC Act eliminated a portion of the federal income tax deduction available to companies that provide prescription drug benefits to retirees under Medicare Part D. We currently are evaluating other prospective effects of the PPAC Act and the related effects on our business.

FAIR VALUE

FAIR VALUE

(15) FAIR VALUE

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

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

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

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

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

Derivative Financial Instruments

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

As of October 1, 2011, there has been no significant impact to the fair value of our derivative liabilities due to our own credit risk as the related instruments are collateralized under our senior credit facilities. Similarly, there has been no significant impact to the fair value of our derivative assets based on our evaluation of our counterparties’ credit risk.

Investments in Equity Securities

Our available-for-sale securities include equity investments that are traded in active international markets. They are measured at fair value using closing stock prices from active markets and are classified within Level 1 of the valuation hierarchy.

Certain of our investments in equity securities that are not readily marketable are accounted for under the fair value option, with such values determined by multidimensional pricing models. These models consider market activity based on modeling of securities with similar credit quality, duration, yield and structure. A variety of inputs are used, including benchmark yields, reported trades, non-binding broker/dealer quotes, issuer spread and reference data including market research publications. Market indicators, industry and economic events are also considered. We have not made any adjustments to the inputs obtained from the independent sources. At October 1, 2011 and December 31, 2010, these assets had a fair value of $7.2 and $8.5, 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 October 1, 2011:

	Fair Value Measurements Using
	Level 1		Level 2		Level 3
Current assets — FX embedded derivatives and FX forward contracts	$	—	$	1.9	$	—
Noncurrent assets — Investment in equity securities and available-for-sale securities	5.1		—		7.2
Current liabilities — FX forward contracts, FX embedded derivatives, and commodity contracts	—		33.7		—
Long-term liabilities — FX embedded derivatives	—		16.6		—

Assets and liabilities measured at fair value on a recurring basis include the following as of December 31, 2010:

	Fair Value Measurements Using
	Level 1		Level 2		Level 3
Current assets — FX embedded derivatives, FX forward contracts and commodity contracts	$	—	$	4.1	$	—

Current liabilities — FX forward contracts and FX embedded derivatives	—		6.1		—
Long-term liabilities — FX embedded derivatives	—		33.2		—

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

	Nine months ended October 1, 2011
Balance at beginning of year	$	8.5
Purchases	—
Losses included in earnings	(1.3		)
Balance at October 1, 2011	$	7.2

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

During the nine months ended October 1, 2011, we recorded an impairment charge of $3.7 to “Special charges, net” related to the rationalization of certain software assets that occurred as a result of the integration of the DS acquisition (see Note 3). The fair value of these assets ($16.2) was determined by obtaining information in the specific markets being evaluated, including the costs incurred to produce similar assets and assumptions about demand in the market for these assets (unobservable inputs — Level 3).

During the nine months ended October 1, 2011, we determined that a trademark held by a business within our Industrial Products and Services segment was impaired and, thus, we recorded an impairment charge of $0.8 to “Special charges, net” during 2011. We determined the fair value of $1.2 by applying an estimated royalty rate to projected revenues, with the resulting cash flows discounted at a rate of return that reflects current market conditions (unobservable inputs — Level 3).

During the nine months ended October 2, 2010, we recorded impairment charges of $4.3 to “Special charges, net” related to idle facilities and certain machinery and equipment (see Note 5). The fair values of these assets ($5.5 and $0.4, respectively) were based on the estimated selling prices. We determined the estimated selling prices by obtaining information in the specific markets being evaluated, including comparable sales of similar assets and assumptions about demand in the market for these assets (unobservable inputs — Level 3).

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

The fair value of our debt instruments, based on borrowing rates available to us at October 1, 2011 for similar debt, was $1,246.4 at October 1, 2011, compared to our carrying value of $1,201.6.
