In the fourth quarter of fiscal year 2019, the Company made a strategic decision that the indefinite-lived trade name of $72.5 million acquired during the acquisition of Nypro would be phased out over the next four years. In connection with a strategic shift to further diversify our portfolio, focus on innovation and technology within the Company’s healthcare business and as a result of the strategic collaboration with a certain medical device company, management decided to implement a rebranding initiative to Jabil Healthcare. Management believes the name change better leverages the Jabil brand and the full range of services available to its customers.

As a result of the decision to rebrand, the Company determined the indefinite-lived trade name should no longer be classified as an indefinite-lived intangible asset. Accordingly, prior to reclassifying the trade name to a finite-lived intangible asset, the Company tested it for impairment and determined the fair value of the asset exceeded the carrying value. As such, this trade name was assigned a four-year estimated useful life and will be amortized on an accelerated basis.

Intangible asset amortization for fiscal years 2019, 2018 and 2017 was approximately $31.9 million, $38.5 million and $35.5 million, respectively. The estimated future amortization expense is as follows (in thousands):
