Goodwill and Other Intangibles

Goodwill is allocated to various reporting units, which are at the operating segment level, for the purpose of evaluating whether goodwill is impaired. Mattel’s reporting units are: (i) North America, (ii) International, and (iii) American Girl. Components of the operating segments have been aggregated into a single reporting unit as the components have similar economic characteristics. The similar economic characteristics include the nature of the products, the nature of the production processes, the customers, and the manner in which the products are distributed.

The change in the carrying amount of goodwill by operating segment for 2018 and 2017 is shown below. Brand-specific goodwill held by foreign subsidiaries is allocated to the North America and American Girl operating segments selling those brands, thereby causing a foreign currency translation impact for these operating segments.

In the third quarter of 2018, Mattel performed its annual impairment tests and determined that goodwill was not impaired since each reporting unit's fair value exceeded its carrying value.

Other Intangibles

Identifiable intangibles were $587.5 million, net of accumulated amortization of $207.9 million, and $639.2 million, net of accumulated amortization of $168.8 million, as of December 31, 2018 and 2017, respectively. The estimated future amortization expense is as follows:



	Amortization Expense

2019	$	40,013
2020	39,496
2021	38,316
2022	37,633
2023	37,153

Mattel had no nonamortizable intangible assets as of and for the year ended of December 31, 2018. Prior to 2018, Mattel tested nonamortizable intangible assets, including trademarks and trade names, for impairment annually in the third quarter and whenever events or changes in circumstances indicated that the carrying values may have exceeded the fair values.

During the third quarter of 2017, Mattel discontinued the use of a trademark which resulted in an asset impairment charge of $9.2 million. The asset impairment charge was recorded within other selling and administrative expenses in the consolidated statements of operations.

Mattel performed its annual impairment assessment during the third quarter of 2017 and determined that its remaining nonamortizable intangible asset was not impaired. In the fourth quarter of 2017, Mattel concluded that a triggering event had occurred related to its nonamortizable intangible asset, and performed an impairment analysis. Based on the result of the interim impairment analysis, it was determined that the nonamortizable intangible asset was not impaired, but that the intangible asset was no longer nonamortizable, and should be amortized starting in the fourth quarter of 2017.

Mattel also tests its amortizable intangible assets for impairment whenever events or changes in circumstances indicate that the carrying value of the asset may not be recoverable. Mattel determined that its amortizable intangible assets were not impaired during 2017. During 2018, Mattel discontinued the use of certain brands and products, which resulted in asset impairments of $4.3 million. Mattel's remaining amortizable intangible assets were not impaired during the year ended December 31, 2018.
