In connection with the acquisitions of Sproutling and substantially all of the assets of Fuhu in the first quarter of 2016, as more fully described in “Note 5 to the Consolidated Financial Statements—Goodwill” of this Quarterly Report on Form 10-Q, Mattel recognized $11.2 million of amortizable identifiable intangible assets, primarily related to patents.

Mattel tests nonamortizable intangible assets, including trademarks and trade names, for impairment annually in the third quarter and whenever events or changes in circumstances indicate that the carrying values may exceed 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 is 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.

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. Amortizable intangible assets were determined to not be impaired during the three and nine months ended September 30, 2017.

During the third quarter of 2017, Mattel established a valuation allowance on certain deferred tax assets, the benefits of which Mattel believes will likely not be realized.
