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 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. There were no transfers between the three levels of the fair value hierarchy for the periods presented.

Parent Guarantees and Bonds Associated with Balcke Dürr — As indicated in Note 4, in connection with the sale of Balcke Dürr, existing parent company guarantees and bank and surety bonds, which totaled approximately Euro 79.0 and Euro 79.0, respectively, at the time of sale (and Euro 76.1 and Euro 47.9, respectively, at December 31, 2017), will remain in place through each instrument’s expiration date, with such expiration dates occurring through 2022. These guarantees and bonds provide protections for Balcke Dürr customers in regard to advance payments, performance, and warranties on projects in existence at the time of sale. In addition, certain bonds relate to lease obligations and foreign tax matters in existence at the time of sale. Balcke Dürr and the Buyer have provided us a full indemnity in the event that any of these guarantees or bonds are called. Also, at the time of sale, Balcke Dürr provided cash collateral of Euro 4.0 and mutares AG provided a guarantee of Euro 5.0 as a security for the above indemnifications (Euro 4.0 and Euro 3.0, respectively, at December 31, 2017). Summarized below are the liability (related to the parent company guarantees and bank and surety bonds) and asset (related to the cash collateral and guarantee provided by mutares AG) recorded at the time of sale, along with the change in the liability and the asset during 2017.



	Twelve Months Ended December 31, 2017
	Guarantees and Bonds Liability			Indemnification Assets
Balance as of December 31, 2016 ^{(1) (2)}	$	9.9		$	4.8
Reduction/Amortization for the period ⁽³⁾	(2.5		)	(2.6		)
Impact of changes in foreign currency rates	1.3			0.6

⁽¹⁾

In connection with the sale, we estimated the fair value of the existing parent company guarantees and bank and surety bonds considering the probability of default by Balcke Dürr and an estimate of the amount we would be obligated to pay in the event of a default. Additionally, we estimated the fair value of the cash collateral provided by Balcke Dürr and the guarantee provided by mutares AG based on the terms and conditions and relative risk associated with each of these securities (unobservable inputs - Level 3).


⁽²⁾	Balance associated with the guarantees and bonds is reflected within “Other long-term liabilities,” while the balance associated with the indemnification assets is reflected within “Other assets.”


⁽³⁾	We reduce the liability generally at the earlier of the completion of the related underlying project milestones or the expiration of the guarantees or bonds. We amortize the asset based on the expiration terms of each of the securities. We record the reduction of the liability and the amortization of the asset to “Other expense, net.”

The net loss recorded at the time of sale of $78.6 includes a charge of $5.1 associated with the estimated fair value of the guarantees and bonds, after consideration of the cash collateral and guarantee provided by Balcke Dürr and mutares AG, respectively.

Goodwill, Indefinite-Lived Intangible and Other Long-Lived Assets — Certain of our non-financial assets 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, 2017, 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.

During the fourth quarter of 2016, we concluded that the carrying value of Heat Transfer’s definite-lived intangible assets (customer relationships and technology) may not be recoverable. As a result, we performed an impairment analysis on such assets. Based on such analysis, we determined that the fair values of these assets were less than their respective carrying values, resulting in an aggregate impairment charge of $23.9. The fair value of the customer relationship intangible asset was based on the estimated future cash flows of the asset, discounted at a rate of return that reflected the relative risk of the cash flows (unobservable inputs - Level 3). The fair values for the technology intangible assets were based on applying estimated royalty rates to projected revenues associated with the assets, discounted at a rate of return that reflected the relative risk of the revenues and current market conditions (unobservable inputs - Level 3).

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 amount discounted at a rate of return that reflects the relative risk of the revenues and current market conditions (fair value based on unobservable inputs - Level 3, as defined above). Based on our annual impairment testing during the fourth quarter of 2016, we recorded an impairment charge associated with Heat Transfer’s trademarks of $2.2. In addition, we recorded impairment charges of $4.0 during the first quarter of 2016 associated with Heat Transfer’s trademarks.

Valuation Methodologies Used to Measure Fair Value on a Recurring Basis

Derivative Financial Instruments — Our financial derivative assets and liabilities include interest rate swaps, 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, 2017, 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.

Indebtedness and Other — The estimated fair value of our debt instruments as of December 31, 2017 and December 31, 2016 approximated the related carrying values due primarily to the variable market-based interest rates for such instruments.
