In connection with the acquisitions of Fuhu and Sproutling, 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 2016, Mattel performed its annual impairment assessments and determined that its nonamortizable intangible assets were 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, 2016.
