There were no intangible asset impairment losses in fiscal 2020. Intangible asset impairment losses of $34.1 million and $5.3 million were recorded as a component of Gain on property dispositions and impairment losses, net, in fiscal 2019 and fiscal 2018, respectively. The fiscal 2019 impairment loss was driven by the continued under performance of the Plated meal kit subscription and delivery operations and primarily relates to the Plated tradename, and to a lesser extent, certain other Plated intangible assets. The fair value was determined using an income approach which included a relief-from-royalty method and relied on inputs with unobservable market prices including the assumed revenue growth rate, royalty rate, discount rate and estimated tax rate. The fiscal 2018 impairment loss primarily relates to underperforming stores.
