Goodwill is tested for impairment at least annually, or more frequently if events or circumstances indicate it might be impaired, using either the qualitative assessment or a quantitative fair value-based test. During the first quarter of 2020, as a result of the significant decline in the Company’s share price and market capitalization and the impact of the COVID-19 pandemic on the Company’s business operations, the Company determined that an interim assessment of goodwill was required. A quantitative assessment was performed for all reporting units as of May 2, 2020. The assessment indicated that the carrying value of the goodwill associated with the Brand Portfolio and Vionic reporting units was impaired, resulting in total goodwill impairment charges of $240.3 million. In addition to the interim assessment, the Company performed an impairment review of the remaining goodwill balance, which is associated with the Blowfish Malibu reporting unit, as of the first day of the fourth fiscal quarter. That review indicated no impairment. During 2019 and 2018, the goodwill impairment testing was performed as of the first day of the fourth fiscal quarter, which resulted in no impairment charges in 2019 and $38.0 million of impairment charges in 2018 associated with goodwill of the Allen Edmonds reporting unit.

Indefinite-lived intangible assets are tested for impairment as of the first day of the fourth quarter of each fiscal year unless events or circumstances indicate an interim test is required. As a result of the triggering event from the economic impacts of COVID-19, an interim assessment was performed as of May 2, 2020. The indefinite-lived trade name impairment review resulted in total impairment charges of $22.4 million for the thirteen weeks ended May 2, 2020, including $12.2 million associated with the indefinite-lived Allen Edmonds trade name and $10.2 million of impairment associated with the indefinite-lived Via Spiga trade name. The remaining carrying value of the Via Spiga trade name of $0.5 million is being amortized over approximately two years. In addition to the interim assessment, the Company tested the indefinite-lived intangible assets as of the first day of the fourth fiscal quarter. As a result of the impairment indicator for Allen Edmonds, the Company also tested the definite-lived Allen Edmonds customer relationships intangible asset. Those reviews resulted in additional impairment totaling $23.8 million, consisting of $19.8 million associated with the Allen Edmonds trade name and $4.0 million associated with the Allen Edmonds customer relationships intangible asset. The Company did not record any impairment charges during 2019. During 2018, an impairment charge of $60.0 million was recorded for impairment of the Allen Edmonds indefinite-lived trade name.
