Other indefinite-lived intangible assets were $109 million and $76 million at December 31, 2020 and 2019, respectively, and principally included registered trademarks. As a result of our 2020 acquisitions, other indefinite-lived intangible assets increased by $32 million as of the acquisition dates. During the first quarter of 2019, we recognized a $9 million impairment charge related to a registered trademark in our Decorative Architectural Products segment due to a change in the long-term net sales projections of lighting products.

We completed our annual impairment testing of goodwill and other indefinite-lived intangible assets in the fourth quarters of 2020, 2019 and 2018. There was no impairment of goodwill for any of our reporting units or of our other indefinite-lived intangible assets in any of these years, other than as disclosed above.

The carrying value of our definite-lived intangible assets was $248 million (net of accumulated amortization of $73 million) at December 31, 2020 and $183 million (net of accumulated amortization of $48 million) at December 31, 2019 and principally included customer relationships with a weighted average amortization period of 15 years in 2020 and 17 years in 2019. Amortization expense, including discontinued operations, related to the definite-lived intangible assets was $24 million, $23 million and $20 million in 2020, 2019 and 2018, respectively. As a result of our 2020 acquisitions, definite-lived intangible assets increased by $86 million, as of the acquisition dates.
