Intangible Assets	Note 6 Intangible AssetsIn February 2021, the FCC announced by way of public notice that UScellular was the provisional winning bidder for 254 wireless spectrum licenses in the 3.7-3.98 GHz bands (Auction 107) for $1,283 million. UScellular paid $30 million of this amount in 2020 and the remainder in March 2021. The wireless spectrum licenses from Auction 107 were granted by the FCC in July 2021. Additionally, UScellular expects to be obligated to pay approximately $185 million in total from 2021 through 2024 related to relocation costs and accelerated relocation incentive payments. Such additional costs were accrued and capitalized at the time the licenses were granted, and are adjusted as necessary as the estimated obligation changes. UScellular paid $36 million, $8 million and $3 million related to the additional costs in October 2021, September 2022 and March 2023, respectively. At March 31, 2023, the remaining estimated payments of approximately $139 million are included in Other current liabilities, and at December 31, 2022, the remaining estimated payments of approximately $133 million and $8 million are included in Other current liabilities and Other deferred liabilities and credits, respectively, in the Consolidated Balance Sheet. The spectrum must be cleared by incumbent providers before UScellular can access it. UScellular does not expect to have access to this spectrum until late 2023.
