Amortization expense associated with these definite-lived intangible assets was $103.6 million, $116.6 million and $73.5 million in 2025, 2024 and 2023, respectively. Amortization expense associated with these intangible assets is expected to be $111.5 million in 2026, $114.1 million in 2027, $109.5 million in 2028, $104.8 million in 2029 and $97.7 million in 2030. The Company amortizes intangible assets with definite lives using either an accelerated method that reflects the pattern in which economic benefits of the intangible assets are consumed and results in higher amortization in the earlier years of the assets’ useful life, or using a straight line method. Approximately 90% of the gross value of definite-lived intangible assets follow an accelerated amortization method.
