Impairments

As a result of Zulily’s deteriorating financial performance during 2019, Zulily initiated a process to evaluate its current business model and long-term business strategy in light of the challenging retail environment. ÌýUpon completing the evaluation of Zulily’s model and long-term strategy, it was determined during the third quarter of 2019 that an indication of impairment existed for the Zulily reporting unit related to its tradename and goodwill. ÌýWith the assistance of a third party specialist, the fair value of the tradename was determined using the relief from royalty method (Level 3), and an impairment in the amount of $580Ìýmillion was recorded during the third quarter of 2019, in the impairment of intangible assets and long lived assets line item in the consolidated statements of operations. With the assistance of a third party specialist, the fair value of the Zulily reporting unit was determined using a discounted cash flow method (Level 3), and a goodwill impairment in the amount of $440Ìýmillion was recorded during the third quarter of 2019, in the impairment of intangible assets and long lived assets line item in the consolidated statements of operations.

The Company performed a qualitative goodwill impairment analysis during the fourth quarter of 2019 and 2018 and determined that triggering events existed at the HSN reporting unit in both periods due to a variety of factors, primarily HSN’s inability to meet its 2019 and 2018 revenue projections. With the assistance of an external valuation expert, the Company determined the estimated business enterprise value of HSN, including its intangible assets and goodwill as of December 31, 2018, and the estimated value of its tradename intangible asset as of December 31, 2019 and December 31, 2018. In 2018 the business enterprise valuation was performed using a combination of a discounted cash flow model using HSN’s projections of future operating performance (income approach) and market multiples (market approach) (Level 3). In both periods the tradename valuation was performed using a relief from royalties method, primarily using a discounted cash flow model using HSN’s projections of future operating performance (income approach) and applying a royalty rate (market approach) (Level 3). As a result of the analysis, HSN recorded a $147 million and a $30 million impairment to its tradename intangible asset as of December 31, 2019 and December 31, 2018, respectively. No impairment of HSN’s goodwill was necessary in 2018.

As of December 31, 2020 the Company had accumulated goodwill impairment losses of $440 million, which was all attributed to the Zulily reporting unit.
