Goodwill

Our goodwill was $143.7 million as of December 31, 2020 and $81.5 million as of December 31, 2019. In the fourth quarter of 2020, we performed a review for impairment of goodwill, and concluded that goodwill was not impaired. The following table summarizes the components of goodwill for the years ended December 31 (in millions):

	2020		2019
Rail North America	$	23.8	$	23.8
Rail International	62.9		57.7
Other	57.0		—
Ending balance	$	143.7	$	81.5

We acquired Trifleet in December 2020. See "Note 5. Business Combinations" for additional information. A preliminary valuation of the acquired net assets of Trifleet resulted in the allocation of $57.0 million to goodwill. We expect to finalize the valuation of the acquired net assets of Trifleet, including the related goodwill, within the one-year measurement period from the date of acquisition.

Other than the goodwill acquired as part of the Trifleet acquisition, changes in the carrying amount of our goodwill for 2020 resulted from fluctuations in foreign currency exchange rates.
