Goodwill

Changes in the carrying amount of goodwill for the three months ended March 31, 2020 are summarized as follows (in thousands):

Balance—December 31, 2019	$	101,224
Cumulative translation adjustments		(189	)
Balance—March 31, 2020	$	101,035

Goodwill is tested for impairment annually on October 31 at the reporting unit level or whenever circumstances occur indicating goodwill might be impaired. The impairment test involves comparing the fair value of each reporting unit to its carrying value, including goodwill. Fair value reflects the price a market participant would be willing to pay in a potential sale of the reporting unit. If the fair value exceeds carrying value, the Company will conclude that no goodwill impairment has occurred. If the carrying value of the reporting unit exceeds its fair value, the Company will recognize an impairment loss in an amount equal to the excess, not to exceed the carrying value. The Company has three reporting units for goodwill impairment testing consisting of its U.S., European, and Brazilian operations. As of March 31, 2020, the Brazilian reporting unit had no associated goodwill.
