In fiscal 2007, UNIFI purchased certain texturing operations that are included in the Polyester Segment. The valuation of the customer list acquired was determined by estimating the discounted net earnings attributable to the customer relationships that were purchased after considering items such as possible customer attrition. Based on the length and trend of the projected cash flows, an estimated useful life of 13 years was determined. The customer list was fully amortized during fiscal 2020 and the customer list and related accumulated amortization was removed from the Consolidated Balance Sheet in fiscal 2020.

A customer list was recorded in connection with a business combination in fiscal 2014, utilizing similar valuation methods as described in the above fiscal 2007 transaction. The customer list is amortized over a nine-year estimated useful life based on the expected economic benefit.

In fiscal 2018, UNIFI purchased certain dyeing assets that are included in the Polyester Segment. The associated non-compete agreement was valued at $1,875 and is amortized using the straight-line method over its five-year term.

UNIFI capitalizes costs incurred to register trademarks primarily for REPREVE^® in various countries. UNIFI has determined that these trademarks have varying useful lives of up to three years and are being amortized using the straight-line method.
