Out-of-period adjustment description | During the six months ended June 30, 2018, TDS recorded an out-of-period adjustment attributable to 2016 and 2017 due to errors in the application of accounting guidance applicable to the calculation of Noncontrolling interests with redemption features related to King Street Wireless, Inc. This out-of-period adjustment had the impact of increasing Net income attributable to noncontrolling interests, net of tax, by $6 million and decreasing Net income attributable to TDS shareholders by $6 million for the six months ended June 30, 2018. TDS determined that this adjustment was not material to any of the periods impacted. The adjustment was made in the first quarter of 2018. |  |  |  |
