Amortization expense for intangible assets was approximately $73.7 million, $102.6 million and $103.6 million for the years ended December 31, 2023, 2022 and 2021, respectively. For the years ended December 31, 2023, 2022 and 2021, the Company removed $7.4 million, $87.7 million, and $171.0 million, respectively, of intangible assets that were fully amortized from the acquired intangible assets and accumulated amortization, which had no net impact on the Company's financial results. In the aggregate, the Company expects the future amortization expense for intangible assets existing as of December 31, 2023 to be approximately $70.8 million, $54.8 million, $43.3 million, $34.7 million and $30.8 million for the years ending December 31, 2024, 2025, 2026, 2027 and 2028, respectively. Intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of such assets may not be recoverable. No impairments of the Company's intangible assets were recognized during each of the years ended December 31, 2023, 2022 and 2021. The Company decided to eliminate usage fees related to agent access to a Homesnap product charged to a specific customer class. This resulted in an acceleration of $16.3 million of amortization expense in 2022 for acquired customer base for this customer class.
