(1)The translation adjustments relate to the periodic translation of Canadian Dollar and South Korean Won denominated goodwill recorded as a part of prior acquisitions in Canada and South Korea, in which the local currency was determined to be the functional currency.

(2)In August 2018, the Company disposed of a business that marketed process heating equipment. See Note 3 - Acquisitions and Disposals for more information about the disposal. The business disposed of constituted its own reporting unit and the amount of goodwill written off was all of the goodwill assigned to that reporting unit. None of the goodwill was considered impaired since the Company recorded a gain on the disposal.
