ASC 350, Goodwill and Other Intangible Assets, requires that goodwill be tested for impairment at the reporting unit level on an annual basis and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of the reporting unit below its carrying value. In the first nine months of 2021, there were no events or circumstances that would have required an interim impairment test. Annually, on October 31, goodwill and other acquired intangible assets with indefinite lives are tested for impairment. Based on the results of the Company’s annual impairment test at October 31, 2020, all reporting units had fair values in excess of their carrying values.

The following table provides the gross carrying value and accumulated amortization for each major class of intangible asset at September 30, 2021 and December 31, 2020:

The Banjo trade name and the Akron Brass trade name are indefinite-lived intangible assets which are tested for impairment on an annual basis in accordance with ASC 350 or more frequently if events or changes in circumstances indicate that the assets might be impaired. Based on the results of the Company’s annual impairment test at October 31, 2020, these indefinite-lived intangible assets had fair values in excess of their carrying values. In the first nine months of 2021, there were no events or circumstances that would have required an interim impairment test on these indefinite-lived intangible assets. The Company uses the relief-from-royalty method, a form of the income approach, to determine the fair value of these trade names. The relief-from-royalty method is dependent on a number of significant management assumptions, including estimates of revenues, royalty rates and discount rates.

Amortization of intangible assets was $16.2 million and $40.7 million for the three and nine months ended September 30, 2021, respectively. Amortization of intangible assets was $11.1 million and $31.1 million for the three and nine months ended September 30, 2020, respectively. Based on the intangible asset balances as of September 30, 2021, amortization expense is expected to approximate $15.7 million for the remaining three months of 2021, $61.3 million in 2022, $58.1 million in 2023, $53.6 million in 2024 and $52.0 million in 2025.
