(1) The change in the gross carrying amount of intangible assets from January 30, 2021 to January 29, 2022 is due to the impact of exchange rate fluctuations.

Indefinite-lived intangible assets are expected to contribute to cash flows indefinitely and, therefore, are not subject to amortization but are subject to annual impairment testing. We test our indefinite-lived intangible assets on an annual basis during the fourth quarter or when circumstances indicate the carrying value might be impaired.

Our trade names consisted of Micromania, our retail operations business in France, which we acquired in 2008; and formerly ThinkGeek, a collectibles retailer, which we acquired in 2015. We no longer operate stores under the ThinkGeek brand. As a result of an impairment test performed during fiscal 2020, we recognized an impairment charge of $0.6 million and $0.5 million and related to our Micromania and ThinkGeek trade names, respectively.

As a result of impairment testing performed during fiscal 2019, we recognized an impairment charge of $2.3 million related to our ThinkGeek trade name. The impairment charge was primarily the result of increases in discount rate assumptions and downward revisions to our forecasted cash flows, consistent with those utilized in the valuation of our reporting units for goodwill impairment testing.

Leasehold rights, the majority of which were recorded as a result of the purchase of SFMI Micromania SAS (“Micromania”) in 2008, represent the value of rights of tenancy under commercial property leases for properties located in France. Rights pertaining to individual leases can be sold by us to a new tenant or recovered by us from the landlord if the exercise of the automatic right of renewal is refused. Leasehold rights are amortized on a straight-line basis over the expected lease term, not to exceed 20 years, with no residual value.

Other intangible assets include design portfolio and favorable leasehold interests. The design portfolio reflects the collection of product designs and ideas that were created by Geeknet and recorded as a result of the Geeknet acquisition, which have been fully amortized. Favorable leasehold interests represent the value of the contractual monthly rental payments that are less than the current market rent at stores acquired as part of the Micromania acquisition. Favorable leasehold interests are amortized on a straight-line basis over their remaining lease term with no expected residual value. As of January 29, 2022, these amounts have been fully amortized.

As of January 29, 2022, the total weighted-average amortization period for our finite-lived intangible assets was approximately 7 years. The intangible assets are being amortized based upon the pattern in which the economic benefits of the intangible assets are being utilized, with no expected residual value.

Intangible asset amortization expense during fiscal 2021, 2020 and 2019 was $3.6 million, $4.0 million and $5.4 million, respectively. The following table presents the estimated aggregate intangible asset amortization expense for the next five fiscal years:
