On September 27, 2012, the FCC conducted a single round, sealed bid, reverse auction to award up to $300 million in one-time Mobility Fund Phase I support to successful bidders that commit to provide 3G, or better, wireless service in areas designated as unserved by the FCC. This auction was designated by the FCC as Auction 901. U.S. Cellular and severalof its wholly-owned subsidiariesparticipated in Auction 901 and were winning bidders in eligible areas within10 states and will receive up to $40 million in one-time support from the Mobility Fund. These funds when received reduce the carrying amount of the assets to which they relate or offset operating expenses.  In connection with these winning bids, in June 2013, U.S. Cellular provided $17 million letters of credit to the FCC, of which $2 million remained outstanding as of December 31, 2016.  U.S. Cellular has received $35million in support funds, of which the entire balance has been spent as of December 31, 2016.  U.S. Cellular has set up a receivable in the amount of $2 million as of December 31, 2016 pending final review from the FCC to release funds.
