NOTE 12. GOODWILL AND INTANGIBLE ASSETS

Goodwill and intangible assets as of December 31, 2015, were the result of our acquisitions of EQ in 2014, Dynecol in 2012 and Stablex in 2010. Changes in goodwill for the years ended December 31, 2015 and 2014 were as follows:

$s in thousands	Environmental Services			Field & Industrial Services			Total
Balance at December 31, 2014(1)	$	152,396		$	65,213		$	217,609
Impairment charges(2)		—			(6,700	)		(6,700	)
Allstate disposition(3)		—			(13,572	)		(13,572	)
Foreign currency translation and other adjustments		(4,704	)		(810	)		(5,514	)

Balance at December 31, 2015	$	147,692		$	44,131		$	191,823


(1)	Balances have been revised to reflect purchase accounting measurement period adjustments related to the acquisition of EQ as disclosed in Note 4.
(2)	As disclosed in Notes 5, on August 4, 2015, we entered into a definitive agreement to sell Allstate to a private investor group for approximately $58.0 million cash, subject to adjustments for working capital and capital expenditures. Allstate represented the majority of the industrial services business we acquired with the acquisition of EQ. As a result of this agreement and management's strategic review, we evaluated the recoverability of the assets associated with our industrial services business. Based on this analysis, we recorded a non-cash goodwill impairment charge of $6.7 million in the second quarter of 2015. We calculated the estimated fair value of the industrial services business using a combination of quoted market prices and discounted cash flows.
(3)	Amounts relate to sale of Allstate as disclosed in Note 5.

Intangible assets as of December 31, 2015 and 2014 consisted of the following:
