In the fourth quarter, the Company tests the carrying value of indefinite-lived trademarks for impairment, as discussed in Note 1, “Summary of Significant Accounting Policies”. In conjunction with the 2020 assessment, the long-term forecast of net sales for a trademark in the Performance Coatings segment was reduced as a result of recent performance. As a result, the Company recognized a pretax impairment charge of $38 million in Impairment charges in the accompanying consolidated statements of income.

The Company’s identifiable intangible assets with definite lives are being amortized over their estimated useful lives. Aggregate amortization expense was $138 million, $136 million and $143 million in 2020, 2019 and 2018, respectively.
