Intangible Assets

Intangible Assets

Intangible assets include transportation agreements and customer relationships that represent a portion of the total purchase price of certain assets acquired from Delek in 2005, from HFC in 2008 prior to HEP becoming a consolidated VIE of HFC, from Plains in 2017, and from other minor acquisitions in 2018.

The carrying amounts of our intangible assets are as follows:

	Useful Life	December 31, 2022		December 31, 2021
		(In thousands)
Delek transportation agreement	30 years	$	59,933	$	59,933
HF Sinclair transportation agreements	10-15 years	75,131		75,131
Customer relationships	10 years	69,683		69,683
Other	20 years	50		50
		204,797		204,797
Less accumulated amortization		(145,497)		(131,490)
Intangible assets, net		$	59,300	$	73,307

Amortization expense was $14.0 million for the years ended December 31, 2022, 2021 and 2020, respectively. We estimate amortization expense to be $9.9 million for 2023, and $9.1 million for 2024, 2025, 2026 and 2027.

We have additional transportation agreements with HF Sinclair resulting from historical transactions consisting of pipeline, terminal and tankage assets contributed to us or acquired from HF Sinclair. These transactions occurred while we were a consolidated variable interest entity of HF Sinclair; therefore, our basis in these agreements is zero and does not reflect a step-up in basis to fair value.
