As of December 31, 2019, the Company recorded a non-cash impairment charge of $6.2 million related to the Ripka Brand trademarks, driven by the timing of the continued transition from a licensing model to a wholesale and direct to consumer model. No other intangible asset impairment charges were recorded for the years ended December 31, 2019 and 2018.

Amortization expense for intangible assets for the years ended December 31, 2019 and 2018 was approximately $3.2 million and $1.1 million, respectively.

The trademarks of the Isaac Mizrahi Brand and the Ripka Brand have been determined to have indefinite useful lives and accordingly, no amortization has been recorded for those intangible assets.

Effective January 1, 2019, and in consideration of the acquisition of the Halston and Halston Heritage trademarks in February 2019, the Company determined that the Halston brand, inclusive of all of its trademarks, including H Halston, and H by Halston, has a finite life of eighteen (18) years, and began amortizing those assets on a straight-line basis accordingly. Prior to January 1, 2019, the H Halston and H by Halston assets were considered indefinite-lived assets.

Estimated future amortization expense related to finite-lived intangible assets over the remaining useful lives is as follows:


($ in thousands)	Amortization
Year Ending December 31,	Expense
2020	$	3,334
2021		3,334
2022		3,334
2023		3,334
2024		3,320
Thereafter		31,539
