Hudson Acquisition
On September 20, 2017, the Company and Chart Sully Corporation, a wholly owned subsidiary of the Company (“Merger Sub”), completed the previously announced acquisition of Hudson pursuant to the terms of the Agreement and Plan of Merger, as amended (the “Merger Agreement”), by and between Chart, Merger Sub, Hudson and R/C Hudson Holdings, L.P., solely in its capacity as the Initial Holder Representative under the Merger Agreement. The acquisition was accomplished by the merger of Merger Sub with and into Hudson, with Hudson surviving the merger as a wholly owned subsidiary of the Company (the “Acquisition”). The preliminary estimated Acquisition purchase price was $419,394, net of cash acquired, including an estimated net working capital adjustment amount of $5,894, and $3,500 in acquisition-related tax benefits acquired, as defined in the Merger Agreement. The total purchase price is subject to further adjustments. Approximately $300,000 of the purchase price was funded through borrowings under the Company’s senior secured revolving credit facility, and the remainder of the purchase price was funded with cash on hand.
Hudson, which has operations in the United States, China and Italy and a joint venture in Mexico, designs, manufactures, sells and services products used in refining, heating, ventilation and air conditioning (HVAC), petrochemical, natural gas, power generation, industrial and commercial end markets.  Hudson is a North American leader in air-cooled heat exchangers and a global leader in axial flow cooling fans. Hudson’s results of operations are included in the Company’s Energy & Chemicals (“E&C”) segment since the date of the acquisition.
The Company preliminarily allocated the acquisition consideration to tangible and identifiable intangible assets acquired and liabilities assumed based on their preliminary estimated fair values as of the acquisition date. The preliminary fair value of the acquired tangible and identifiable intangible assets were determined based on inputs that are unobservable and significant to the overall fair value measurement. It is also based on estimates and assumptions made by management at the time of the acquisition. As such, this was classified as Level 3 fair value hierarchy measurements and disclosures.
The Company estimated the preliminary fair value of acquired unpatented technology and trademarks and trade names using the relief from royalty method. The preliminary fair values of acquired customer backlog and customer relationships were estimated using the multi-period excess earnings method. Under both the relief from royalty and multi-period excess earnings methods, the fair value models incorporate estimates of future cash flows, estimates of allocations of certain assets and cash flows, estimates of future growth rates, and management’s judgment regarding the applicable discount rates to use to discount such estimates of cash flows. The estimated useful lives of identifiable finite-lived intangible assets range from two to 12 years.
Hudson complements Chart’s E&C segment with the addition of its Fin-Fan® brand and other air cooled heat exchangers which broaden E&C’s end market diversity from primarily liquefied natural gas, industrial and natural gas to include HVAC, petrochemical and power generation.  The addition of Hudson’s fans business, known by the Tuf-Lite® and Cofimco® brands, allows E&C to offer a broader technology solution for Chart’s customers. Management anticipates the combination of strong engineering cultures will continue to further develop full service solutions for Chart’s customers. The preliminary estimated goodwill was established due to the benefits outlined above, as well as the benefits derived from the anticipated synergies of Hudson integrating with Chart’s E&C segment. Goodwill recorded for the Hudson acquisition is not expected to be deductible for tax purposes.
The acquisition consideration allocation below is preliminary, pending completion of the fair value analyses of acquired assets and liabilities as well as certain other analyses. The excess of the purchase price over the estimated fair values is assigned to goodwill. As additional information becomes available, the Company may further revise the preliminary acquisition consideration allocation during the remainder of the measurement period, which shall not exceed twelve months from the closing of the acquisition. Any such revisions or changes may be material.
The following table summarizes the estimated fair values of the assets acquired and liabilities assumed in the Hudson acquisition:

Contingent Consideration
The estimated fair value of contingent consideration relating to the 2015 D&S Thermax acquisition was $1,800 at the date of acquisition and was valued according to a discounted cash flow approach, which includes assumptions regarding the probability of achieving certain earnings targets and a discount rate applied to the potential payments. Potential payments may be paid between October 1, 2017 and July 1, 2019 based on the attainment of certain earnings targets. The potential payments related to Thermax contingent consideration are between $0 and $11,288.
Valuations are performed using Level 3 inputs as defined in the Fair Value Measurements note and are evaluated on a quarterly basis based on forecasted sales and earnings targets. Contingent consideration liabilities are classified as other current liabilities and other long-term liabilities in the condensed consolidated balance sheets. Changes in fair value of contingent consideration, including accretion, are recorded as selling, general, and administrative expenses in the condensed consolidated statements of operations and comprehensive income.
The following table represents the changes in contingent consideration liabilities:

Decrease in fair value of contingent consideration liabilities
(1,622
)
Balance at September 30, 2017
$

For the nine months ended September 30, 2017, the fair value of contingent consideration decreased by $1,622, which was primarily driven by economic circumstances that significantly reduced the likelihood of achieving certain earnings targets for the duration of the remaining potential payout period. There was no change in contingent consideration for the three months ended September 30, 2017. For the three and nine months ended September 30, 2016, the fair value of contingent consideration increased by $75 and $122, respectively.
